Let’s start with the rectangle. 6(4) = 24 cm^2.
The triangle is 1/2(bh).
We know the bottom of the triangle is 4 because 10-6=4.
4(4) = 16
16/2 = 8
We’re at 32 square cm so far.
Now the semi circle.
The diameter is 4, so the radius is 2.
A = (pi)r^2
A = (pi)4
A= 4pi
Best estimate could be expressed as 32 + 4pi cm^2, or substituting 3.14 for pi, 44.56 cm^2

An equation is shown below:
IrinaK [193]
5(2x - 8) + 15 = -15
               -15      -15     subtract 15 from each side
5(2x - 8) = -30
  ÷5             ÷5             divide both sides by 5
2x - 8 = -6
     +8    +8                   add 8 to each side
2x=2
÷2  ÷2                          divide both sides by 3
x = 1

Checking:
5(2(1)-8) + 15 = -15
5(-6) + 15 = -15
-30 + 15 = -15
-15 = -15             Correct! x=1
