help, how to write the correct solution set (43x)^2=39?

Expand (43x)^2

Frank1991 Group TitleBest ResponseYou've already chosen the best response.0
If you expand it you get: (43x)*(43x)=9x^2 24x +16
 2 years ago

Frank1991 Group TitleBest ResponseYou've already chosen the best response.0
and then = 9x^2 24x +16 39 =0=9x^2 24x 23

Frank1991 Group TitleBest ResponseYou've already chosen the best response.0
and use the abc formula

@ Frank 1991yes I got what you where saying

i see what you have here, and i have similar, I guess I need to simplify this because it does not show in my options in labs
 2 years ago

johnson32 Group TitleBest ResponseYou've already chosen the best response.1
@Frank1991, i meant have to simplify all radicals. heck its multiply choice

use the square root property to solve for the equation. (x9)^2=64
 2 years ago

Frank1991 Group TitleBest ResponseYou've already chosen the best response.0
in the last case you could say \[\sqrt{(x9)^{2}}=\sqrt{64}=8=x9\]

so x = 8+9

@Frank1991, my answers are as yours, but when i type them in them in the computer labs they come back wrong.

oh that is strange you could check what wolframalpha is saying

johnson32 Group TitleBest ResponseYou've already chosen the best response.1
@Frank1991 sure thing

Yes wolfram alpha is also saying something different

I forgot about that a sqaure could also be negative

Frank1991 Group TitleBest ResponseYou've already chosen the best response.0
so we got one answer but forgot about the second

@Frank1991 .. thanks

The formula A=P (1+r)^2 gives the amount A in dollars that P dollars will grow to in 2 years interst rate r ( where r is given as a decimal), using compound intreset. What interest rate will cause $3000 to grow to $3370.80 in 2 years..

The formula S=16t^2 is used to approximate the distance S, in feet, that an object falls freely from the rest in t seconds. The height of a building is 1048 feet. How long would it take for an object to fall from the top?
 2 years ago

Frank1991 Group TitleBest ResponseYou've already chosen the best response.0
To the first question:3000=3370.8(1+r)^2 => 3000=3370.8 (r^2 +2r +1) => r^2 +2r +1 = 3000/3370.8 => r^2 +2r +(13000/3370.8) = 0 and solve this for r. Probably one of the answers is negative and that makes no sense

I hope it helped @johnson32

@Frank1991 , so you got 0% interest rate,

johnson32 Group TitleBest ResponseYou've already chosen the best response.1
@mayankdevnani , yes thank you got that one solve already

no r is the intrest rate

@Frank1991 , I got 65.5 seconds for the object falling at

Frank1991 Group TitleBest ResponseYou've already chosen the best response.0
so use the quadratic formula for: r^2 +2r +(13000/3370.8) = 0 and r would be your answer
 2 years ago

Frank1991 Group TitleBest ResponseYou've already chosen the best response.0
oh the 3000 and 3370.8 should switch

You obtain r = 2.06 or r=0.06
 2 years ago

Frank1991 Group TitleBest ResponseYou've already chosen the best response.0
r=2.06 makes no sense because there is an increase not a decrease, so your final answer is 0.06
