which correctly shows the area formula for a trapezoid, A= 1/2 h (b1 + b2)

Answered by ri
what is the undefined value for the equation 14 = 7x/9+4x
Answered by GPT-4
The equation that has the solution set {-3} is

4x+8=-4.

If we solve this for x:

4x = -4 - 8

4x = -12

x = -12 / 4

x = -3.

The area formula for a trapezoid is correctly shown as:

A = 1/2 * h * (b1 + b2)

where:
A is the area of the trapezoid,
h is the height of the trapezoid,
b1 and b2 are the lengths of the two bases of the trapezoid.

To find the undefined value for the equation, set the denominator equal to zero and solve for x.

So, to find the undefined value, set 9+4x = 0.

Then we get 4x = -9, so x = -9/4 = -2.25.

So, the undefined value for the equation is x = -2.25 because it would make the denominator zero and division by zero is undefined in mathematics.
