2(4x+5)+2(x+15)=360
8x+10+2x+30=360
10x=320
x=32
∠A=4×32+5=133º
11: 6(3x+4y)
13a: 5x(3-4y)
13b: they but “x” next to 4 when the expression didn’t have the “x^2” anywhere
14a: find the common factors of each number
The area of the given figure is 38 square units
<h3>Area of a trapezoid</h3>
The area of the given trapezoid is expressed as:
A = 0.5(a+b)h
where
a and b are the sides
h is the height
Substitute
A = 0.5(9+10) * 4
A = 19 * 2
A = 38 square units
Hence the area of the given figure is 38 square units
