Answer:
10/2x^2+2x+2=2x-1+y
y=5x^2+1
Step-by-step explanation:
5x^2+4
perimeter=2w+2l
10x^2+4x+4=2(2x-1)+2l
10x^2+4x+4-2(2x-1)=2l
10x^2+4x+4-4x+4=2l
10x^2+8=2l
l=5x^2+4
6x^2 + 4x
g(x) + f(x)
= -8x^2 - 3x + 5 + 2x^2 + 7x - 5
= -8x^2 + 2x^2 - 3x + 7x + 5 - 5
= - 6x^2 + 4x
54.5%
The numbers are 11 and 65
11 + 65 = 76
65 - 11 = 54
