1470=b+g
1/3b=1/4g+105
b=1470-g
1/3(1470-g)=1/4g+105
490-1/3g=1/4g+105
1/4g+1/3g=490-105
7/12g=385
g=660
b=1470-g
b=1470-660
b=810
if p(x) = -2x²-3x+1, find p( -2)

We know: length of a rectangle is 7m less than three times the width.
So let's set the length to l, width to w.
And we can get that l = 3w-7.
We also know that the area of the rectangle is 66 m^2.
Thus, l*w= 66.
So we have:
function 1: l=3w-7
function 2: l*w=66
plug function 1 to 2.
(3w-7)*w=66
3w^2-7w-66=0
w=6 and -11/3.
And the width of a rectangle can not be negative.
So: w=6.
Plug w=6 back to function 1 or 2, either way is correct and can give you the length. In this case, I will plug it back to function 1.
l=3*6-7=11.
So: the width of the rectangle is 6, and the length of the rectangle is 11.

Step-by-step explanation:
If this is a school paper, at the bottom or top there is usually a site. In this site, you search it up and type answer key. Then, if you are lucky the link would sent you to the answer key. If not, you can search up on yt how to do this such as x, y, z if still you can join study groups on cord. And lastly, if none of those work try messaging some friends. I wish you luck,
