If the area of the trapezoid below is 75 square units, what is the value of x? A. 12 units
B. 6 units
C. 1.5 units
D 3 units

area of trapezoid= 1/2 × ( a + b ) × high

75cm² = 1/2 × (8+17) × h

75. = 1/2 × 25 × h

75. = 12,5 × h

75. = 12,5h

h = 75 ÷ 12,5

h. = 6 ( B )

37/3

step-by-step explanation:

step 1: simplify both sides of the equation.

7x+8(x+

)=3(6x−9)−8

7x+(8)(x)+(8)(

)=(3)(6x)+(3)(−9)+−8(distribute)

7x+8x+2=18x+−27+−8

(7x+8x)+(2)=(18x)+(−27+−8)(combine like terms)

15x+2=18x+−35

15x+2=18x−35

tep 2: subtract 18x from both sides.

15x+2−18x=18x−35−18x

−3x+2=−35

step 3: subtract 2 from both sides.

−3x+2−2=−35−2

−3x=−37

step 4: divide both sides by -3.
