Answer:
The area of one trapezoidal face is 2 square inch
Step-by-step explanation:
Area of a trapezoid is calculated as follows:
A = (a + b)/2 * h
where a, b and h are the lengths of the top side, the base and the height, respectively. Replacing with data:
A = (1 + 3)/2 * 1
A = 2 square inch
2x² - 4x - 30
2(x²) - 2(4x) - 2(15)
2(x² - 4x - 15)
