The area of a trapezoid is calculated by the equation,
A = 0.5(b₁ + b₂)h
where b₁ and b₂ are the bases and h is the height. When we substitute the given expression for the dimensions in the given,
A = 0.5(4x + 2x)(x - 6)
A = 0.5(6x)(x - 6) = 3x² - 18
Thus, the answer is letter A.
Since the slope is in the form y/x, and since, with each number in the y column, the value is subtracted by 4, the slope is -4, and the y intercept is (0,1).
So, the equation is y=-4x+1
Distribute the six: 6y+6x
