width = w
length = w +2
perimeter = 2L + 2w
40 = 2(w+2) + 2w
40 = 2w+4 +2w
40 = 4w+4
36=4w
w=36/4 = 9
with = 9
length = 9+2 = 11
area = l x w = 9*11 = 99 square cm
Okay this one is easy all you gotta do is look at the decimal point and the place its at.
Answer:
(x+3)(x-4)^2
Step-by-step explanation:
= (x+3)(x^3-5x^2-8x+48)/(x+3)
= x (x^3-5x^2-8x+48)/(x+3)
= x^2-8x+16
= (x+3)(x-4)(x-4)
= (x+3)(x-4)^2
Answer:
-18
Step-by-step explanation:
Simplify: |3 – 10| – (12 / 4 + 2)^2

Hope this helps!
I think its C but not sure
