We can represent the width as x and the length as x+5. Then we can make the area formula A=(x)*(x+5), plug in 36 for A, and solve for x
36=x^2+5x (distribute)
0=x^2+5x-36
0=(x+9)(x-4)
So x=-9 and 4 but dimensions can't be negative so x=4
So if the width is 4, then the length is 9 (4+5)
Hope this helps :)

Answer:
-1
Step-by-step explanation:
let,x=-1
f(x)= 12/4x + 2
f(-1)= 12/4x(-1) + 2
=12/(-4) +2
= -3+2
= -1
Answer:
-3
Step-by-step explanation:
there is -7 on the right side, so to get -7 on the left, x would have to equal -3
(-3)2=-6 + (-1) =-7
Yes you would multiply them
