To do this problem, we must first distribute the 13 and 14 into the parenthesis.
<span>13(9−6m)+14(12m−8)
117 - 78m + 168m - 112
To combine like terms, we can add/subtract terms that have an "m" together and then we can add/subtract terms that do not have "m" together.
117 - 112 = 5
and
168m - 78m = 90m
So our final sum is 5 + 90m</span>

Answer: 64 cm^2</h3>
Reason:
The parallelogram has area of A = base*height = 10*7 = 70 cm^2
The white rectangle has area of B = base*height = 3*2 = 6 cm^2
The shaded region has area of A - B = 70 - 6 = 64 cm^2
If you are curious why the rectangle and parallelogram use the same formula to get the area, notice how you can move that triangle on the left toward the right side so that a rectangle can be formed.
Answer:
Step-by-step explanation:
we know that
The volume of the sphere is given by the formula
we have that
----> the radius is half the diameter
