The complete question in the attached figure
we know that
if AC=22
then AE=AC/2----------> 22/2----------> AE=11
so
2x-5=11----------> 2x=16---------> x=16/2--------> x=8
the answer is x=8
Surface area of the the rectangles:
8 * 5 + 8 * 4 + 8 * 3 = 96
Surface area of the two triangles:
Use bh/2 base time height over 2
(4 * 3)/2 = 6
There are 2 triangles, 2 * 6 = 12
12 + 96 = 108
Answer:
b. x = 1
Step-by-step explanation:
(1^2+3x)=(1^2+1+2) is equal to 4
Your answer would definitely be the 3rd answer choice.
