Answer:

Yes, you can add them together.

Step-by-step explanation:

In algebra, like terms are terms that have the same variables and powers. The coefficients do not need to match. Unlike terms are two or more terms that are not like terms, they do not have the same variables or powers. The order of the variables does not matter unless there is a power.

The area of the trapezoid is 40 square units.

Whitepunk [10]

Answer:

5 units

Step-by-step explanation:

Image of the trapezoid is attached.

To find the height of the trapezoid (image attached), let's take the formula for area of a trapezoid.

The formula for area of a trapezoid is:

$A = (\frac{a + b}{2}) h$

Here, a and b represents the bases of the trapezoid.

a = 6

b = 10

h which represents height is unknown.

A = 40

Substitute figures:

$40 = (\frac{6 + 10}{2}) h$

$40 = (\frac{16}{2}) h$

$40 = 8 * h$

Solve for h:

$h = \frac{40}{8}$

$h = 5$

The height of the trapezoid is 5 units
