11.) 13+x
community property
12.) 8x-12
distributive property
13.) (2+a)+b
14.) 4(2x+1)= 4+8x
For question 14 you can do 4×2=8x. Then do 4×1=4. It is equal. Just do distributive property for number 14 for 4(2x+1)
Volume = π (3.14)×22^2×12.5 = 18,997 inches³
3/5 = 9/15 = 36/60
2/3 = 10/15 = 40/60
0.65 = 65/100 = 13/20 = 39/60
Therefor, the answer is 3/5, 0.65, 2/3.
Number of angles = number of sides
180 - 120 = 60 (calculating the exterior angle)
360 / 60 = 6
There are 6 sides.
Hope this helps! :)
