3 terms are correct! 5x^2 > one term +x >2nd term 10 > 3rd term but the constant is the term with no ''x" in it, which is ... ?

janice1989Best ResponseYou've already chosen the best response.0
So the answer would be A than correct?

yes, A would be correct.

Janice, thanks for using OpenStudy. Do tell other parents about us. Hartnn is one of our senior, most skilled and patient OpenStudiers! There are many like him on the site to help. They do it because they love Math and helping young learners.

the expression 9x^25x7 has __ terms and a constant of ___ 3,7 5,7 3,7 5,7 He said there is 5 terms and a constant of 7 since its right after the x. so he said it would be B correct?
 7 months ago

janice1989Best ResponseYou've already chosen the best response.0
I will for sure tell other parents about it! Ive been stuck on this for such a long time, And someone told me about it, this is an amazing website, Do you also do Geometry?? My daughter is doing geometry and also has special needs she has Aspergers and is having such a hard time with it.. and she is just stressed and all!
 7 months ago

hartnnBest ResponseYou've already chosen the best response.4
thank you for the appreciations, yes, i do geometry too :) lets count the terms in , 9x^25x7 9x^2 5x 7 how many ?
 7 months ago

janice1989Best ResponseYou've already chosen the best response.0
Than after we finish this up maybe later on you could help my daughter? And he said 3 :)
 7 months ago

janice1989Best ResponseYou've already chosen the best response.0
so instead he said would it be A than?

In 6x^43y+5x^410 what are the like terms in the expression choose all that apply.. 6x^4 3y 5x^4 10 he said all of them

you will find many amazing users here on OpenStudy, willing to help you as much as i am :)

hartnnBest ResponseYou've already chosen the best response.4
like terms are those which have same exponent of 'x' like x^3, 3x^3, 8x^3 .... (one set of like terms) x,4x,9x,x,.... and constants like 4,8,0,1,....
 7 months ago

hartnnBest ResponseYou've already chosen the best response.4
in 6x^43y+5x^410 which terms have same exponent of x ?
 7 months ago

janice1989Best ResponseYou've already chosen the best response.0
so would it be A & C
 7 months ago

hartnnBest ResponseYou've already chosen the best response.4
does your boy say/agree with A and C too ?

janice1989Best ResponseYou've already chosen the best response.0
Yeah he said that, i am just typing for him because he is little bit slow on typing! :D

tell him he is absolutely correct :)

Okay :D hold on he is working on next one to see if he can get it, who would have known a stranger online could help so much more than a teacher!

Simplify : 7x^2+2x^2 7x^2 9x^2 14x^4 9x^4 He said he is not sure what to do can you explain it step by step? He said it would either be A or B since the top number are both 2. or do you add them together?
 7 months ago

janice1989Best ResponseYou've already chosen the best response.0
He said would it be B? since 7+2 = 9??
 7 months ago

hartnnBest ResponseYou've already chosen the best response.4
the top number (here 2) is called the exponent. does he know what an exponent is ? and yes, B is correct, because 7x^2+2x^2 = (7+2)x^2 = 9x^2
 7 months ago

janice1989Best ResponseYou've already chosen the best response.0
He said hes heard of it, but isnt really sure what it is.
 7 months ago

hartnnBest ResponseYou've already chosen the best response.4
i'll explain, x^n, x is called the 'base' and n is called the exponent. x^n implies , multiplying 'x' to itself, 'n' times. we take an example : 2^4 will imply multiplying 2 4 times = 2*2*2*2 = 16 similarly, x^2 will imply multiplying x with itself twice, x*x got this ?
 7 months ago

janice1989Best ResponseYou've already chosen the best response.0
he said oh that is what exponent is i know now! lol. Thank you, hes working on the next one :)

Subtract the second expression from the first (5x^23x+5)(3x^24x7) 2x^2+x+12 2x^27x+12 8x^2+x+12 2x^2+x2 He said would it be B?
 7 months ago

hartnnBest ResponseYou've already chosen the best response.4
why B , how did he get coefficients like 2,7 and 12 ?
 7 months ago

janice1989Best ResponseYou've already chosen the best response.0
He says he dont know, i think he was guessing. He does that a lot. Im sorry!
 7 months ago

hartnnBest ResponseYou've already chosen the best response.4
(5x^23x+5)(3x^24x7) = 5x^2 3x +5 3x^2  (4x)  (7) {by distributing the negative} = 5x^2 3x +5 3x^2 +4x +7 {because negative times negative becomes positive!} then we identify like terms. but is this much clear ?
 7 months ago

janice1989Best ResponseYou've already chosen the best response.0
he said for like terms would it be 5x^2 3x 3x^2 and 4x?
 7 months ago

hartnnBest ResponseYou've already chosen the best response.4
for like terms , the exponent of x should be same, for which terms exponent of x is 2 ? for which terms exponent of x is 1 ?
 7 months ago

hartnnBest ResponseYou've already chosen the best response.4
note x means x^1 , both mean the same
 7 months ago

janice1989Best ResponseYou've already chosen the best response.0
he said he is confused. he said he dont get that,
 7 months ago

hartnnBest ResponseYou've already chosen the best response.4
ok, the 5x^2 and 3x^2 has exponent of 2 so these are like terms and we can combine them in this way, 5x^23x^2 = (53)x^2 = 2x^2 got this?
 7 months ago

hartnnBest ResponseYou've already chosen the best response.4
cool, from this : 5x^2 3x +5 3x^2 +4x +7 the other like terms are 3x and +4x (because they both contains just x with it, not x^2 or x^3 .....) so we can combine them like : 3x+4x = (3+4) x = ... ?
 7 months ago

janice1989Best ResponseYou've already chosen the best response.0
he said uh he thinks you can combine them not 100% sure
 7 months ago

hartnnBest ResponseYou've already chosen the best response.4
yes, they can be combined because they both have same exponent (=1 here) so, 3x+4x = (3+4) x = x lastly, what remains are just constants, 7+5 , which =12

janice1989Best ResponseYou've already chosen the best response.0
he understands whats next step?

distribute and simplify 7(2x4)+2(3x+1) 20x+26 20x26 14x28 6x+2 He asked what is it to distribute???
 7 months ago

hartnnBest ResponseYou've already chosen the best response.4
Distribution Property : a(b+c) = ab+ac dw:1379629904908:dw ask if you need an explanation in words....
 7 months ago

janice1989Best ResponseYou've already chosen the best response.0
ok he said he got it so far
 7 months ago

hartnnBest ResponseYou've already chosen the best response.4
dw:1379630067115:dw so can he fill that now ?
 7 months ago

hartnnBest ResponseYou've already chosen the best response.4
the operation is actually of multiplication while distributing, a(b+c) = a*b + a*c so, that will be = 7*(2x) + 7*(4) got this ? and simplify this further
 7 months ago

janice1989Best ResponseYou've already chosen the best response.0
14 &28correct he said?
 7 months ago

hartnnBest ResponseYou've already chosen the best response.4
yeah, just don't forget the 'x' too 7*2x = 14x 7*(4)=28 so, the first part 7(2x4) = 14x28 in same way, please try the second part, 2(3x+1)
 7 months ago

hartnnBest ResponseYou've already chosen the best response.4
good! and whats 2*3x = ... ?
 7 months ago

hartnnBest ResponseYou've already chosen the best response.4
2*3x = 6x (again, don't forget the 'x') so we have 7(2x4) +2(3x+1) = 14x28+6x+2 we have distributed successfully, now time to combine like terms, tell him to try first.

janice1989Best ResponseYou've already chosen the best response.0
2x, 3x?? and 14x and 6x?
 7 months ago

hartnnBest ResponseYou've already chosen the best response.4
from this 14x28+6x+2 there are only 2 terms containing 'x' , right ? so what is 14x+6x =....?

hartnnBest ResponseYou've already chosen the best response.4
the constants, 28+2 =... ? and so the final answer will be ?

evaluate the expression 2(x+y)  for x=6 and y=7 3 13/3 19/3 20/3 26/3 he said its look like this 2(6+7)  3 he said would the answer be 26/3??

Evaluate the expression 3x+4y  x=1.5 and y=2.5 2 2 4.25 6.25 7.25 His work 3(1.5) +4(2.5)  2 would it be 7.25?
 7 months ago

hartnnBest ResponseYou've already chosen the best response.4
lets check, 3(1.5) + 4(2.5) = 4.5+10 = 14.5 is the numerator. and 14.5/2 = 7.25 is the correct answer! :) :)
