a) -x2 - 9
b) -x2 - 1
c) -x4 - 9
d) -x4 - 1

A is the correct answer

Step-by-step explanation:

( 2x * 2 -5) - (3x* 2 +4)

= 4x - 5 - 6x -4

= -2x -9 = -x2 -9

Hope this help you :3

b

step-by-step explanation:

the total is 23.97. 0.25% is off so you have to subtracting 25% from 100% and you will get 75% if you convert it to decimal you will get 0.75. you have to find the original because the formula is % times original = total.so you have the total and the % so you just have to plug it in.

area = length x width

length = 2 x width

32 = 2 x width x width

32 = 2 x width^2

36 = width ^2  

width = 6

length = 12

area is 32

perimeter = 2 x 12 + 2 x 6 = 24 + 12 = 36
