Answer:
<u>x = 54 and none of the alternatives given is correct</u>
Step-by-step explanation:
Let's solve for x in the equation given, this way:
2/3 ÷ 3x = 12
2/3 * x/3 = 12
2x/9 = 12
2x = 108
x = 108/2 = 54
Proof of x = 54
2/3 * 54/3 = 108/9 = 12
<u>x = 54 and none of the alternatives given is correct</u>
Answer is B
area for a trapezoid is [( Base 1 + Base 2 ) * height] /2
