I need some really good help for alot of work. I got behind in math bc of life in general. I have been playing catch up but am now stuck with 5 days to finish 7 unit /semester assesments. Can somebody please please help me get it done. I have one other course i am trying to finish in this same time frame. It is 8th grade intermediate math.
1.Simplify.
–1 + 5(6 – y)
A.–y + 5
B.–y + 29
C.–5y + 29
D.–5y – 31
2. u NEGATIVE 3 =1/125
U=
3. What is the product written in scientific notation?
(2.1 × 10 NEG. 2)(3.2 × 10 NEG. 4)

Best ResponseYou've already chosen the best response.01. The answer is C. This is because you have to expand the brackets 1+5(6y) The 1 remains the same but the bracket changes. 1+305y This is because the 5*6 is 30 and 5*y is 5y This can be simplified to 295y or 5+29

Best ResponseYou've already chosen the best response.02. The answer is: U =5 first, you take the U^3 and put it as 1/U^3, that is because you cannot have a negative exponent, you MUST turn the exponent into a positive.... now you have 1/U^3 = 1/125... now you find the uncubed version of 125:::::: the cube root of 125 is 5 so, when you have U^3, you are looking at 5^3..
