The answer to your question is x=3
Answer:
3 cm
Step-by-step explanation:
Set up an equation that solves for the surface area, "112
" :
10(2)+10(2)+2x+2x+10x+10x = 112
20+20+4x+20x = 112
24x+40=112
24x=72
x=3
So, 3 cm.
It is C. Associative property of multiplication
Here
45 :72 = 40:p
Or 45/72=40/p
Or 45p = 72*40
Or p = 2880/45
Or p= 64
