Answer:

x=3

Step-by-step explanation:

1st distribute

8x-6-8=4+2x

2nd add

8x-14=4+2x

3rd move like terms

8x-2x=4+14

4th add the numbers

6x=18

5th divide both sides by 6

The height of a trapezoid is 8 inches and its area is 96 in one base of the trapezoid is 6 inches longer than the other base wha

yan [13]

First is to get the given data that we might be able to use for computation.
H = 8 inches
Area = 96
B1 = B1
B2 = B1+6

Next is to know the area of a trapezoid
Area = H x (B1 + B2)/2
96 = 8 x (B1 + B1 + 6) / 2
96 = 8 x (2B1 + 6) /2
96 = 4 x (2B1 + 6)
14 = 2B1 + 6
2B1 = 8
B1 = 4
B2 = 10
