Answer:
1)
Isolate for the variable m
-13 = 5 + 20m -2m
-13 = 5 + 18 m
-18 = 18 m
m = -18/18
m = -1
2) same thing
11 + 8r = -r +29
8r + r = 29 - 11
9r = 18
r = 18 / 9
r = 2
3) same thing
4x +6 +3 = 17
4x = 17 - 6 - 3
4x = 17 - 9
4x = 8
x = 8 /4
x =2
4) Same thing
-8(-8x - 6) = -6x -22
64x +48 = -6x -22
64x +6x = -22 -48
70x = -70
x= -70/70
x = -1

Answer:
A = 70 mm²
Step-by-step explanation:
The area (A) of a trapezoid is calculated as
A = 
h (b₁ + b₂)
where h is the perpendicular height and b₁, b₂ the parallel bases
Here h = 10, b₁ = 10, b₂ = 4 , then
A = × 10 × (10 + 4) = 5 × 14 = 70 mm²
