The area of a trapezoid is given by the formula A = 1/2h(B + b). Solved for b, this formula becomes b = A) 1 2 hA -B B) 1 2 hB - A C) 2A - B h D) 2A h - B

Option D: is the value of b

Explanation:

Given that the formula for the area of a trapezoid is

We need to solve the formula for b.

The value of b:

Let us solve the formula to determine the value of b.

Multiplying both sides of the formula by 2, we get;

Dividing both sides by h, we get;

Subtracting both sides of the formula by B, we have;

Thus, the value of b is

Hence, Option D is the correct answer.

the direct variation says that:

then the equation is of the form is given by:

            where k is the constant variation.

from the given table:

consider any value of x and m(x)=y

x = 2 and m(x)=y = 3

substitute these value in [1]; we have;

divide both sides by 2 we get;

⇒

check:

put x = -1 and m(x) = -1.5

substitute in the equation:

-1.5 = -1.5                   true

therefore, the function m(x) represents a direct variation
