What is 8a + 8a?
| 64a | |
| 16 | |
| 0 | |
| 16a |
To combine like terms, add or subtract the coefficients (the numbers that come before the variables) of terms that have the same variable raised to the same exponent.
8a + 8a = 16a
The formula for the area of a circle is which of the following?
a = π d2 |
|
a = π r2 |
|
a = π d |
|
a = π r |
The circumference of a circle is the distance around its perimeter and equals π (approx. 3.14159) x diameter: c = π d. The area of a circle is π x (radius)2 : a = π r2.
Simplify 9a x 5b.
| 45ab | |
| 45\( \frac{b}{a} \) | |
| 14ab | |
| 45\( \frac{a}{b} \) |
To multiply monomials, multiply the coefficients (the numbers that come before the variables) of each term, add the exponents of like variables, and multiply the different variables together.
9a x 5b = (9 x 5) (a x b) = 45ab
