Add the top and bottom together, divide by 2, then multiply by the height:
Area = (7.5 + 2.5)/2 x 2.5
Area = 10/2 x 2.5
Area = 5 x 2.5
Area = 12.5 square units.
The answer is <span> </span><span>C(x) = 550x + 1200

There's one unforgivable taboo that transcends just about every branch of mathematics, and that's dividing by zero. Division by zero is undefined, so any fraction with a zero in its denominator is by definition absurd. For what values of x would the denominators on either of those fractions be zero? Those will define the restrictions on your variable.
I’d say the answer would be d
