| 72 |
The area of a parallelogram is equal to its length x width:
a = l x w
a = a x b
a = 4 x 3
a = 12
What is 5a + 7a?
| -2a2 | |
| -2 | |
| 35a2 | |
| 12a |
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.
5a + 7a = 12a
