Answer:
B. 66 square inches
Step-by-step explanation:
Area of a trapezoid = (a + b) / 2 * h
a = base a = 14 inches
b = base b = 8 inches
h = height = 6 inches
Area of a trapezoid = (a + b) / 2 * h
= (14 inches + 8 inches) / 2 * 6 inches
= 22 inches / 2 * 6 inches
= 11 inches * 6 inches
= 66 inches²
Area of a trapezoid = 66 inches²
Answer:
7: (3,9) 8:(-2,1) 6: (2,10)
Step-by-step explanation:
7) 2x+3=-2x+15
x=3
y=2(3)+3
y=6+3
y=9
8)x= -1(1+2y)/3
-4-2y=-6
y=1
x=-2(1+2(1))/3
x=-2
6)2x-16=-12
x=2
y=2+8
y=10
Yes because if you write it it's twenty nine out of one hundred
The width is 5 feet because 5×2=10 which is the area.
