When solving an equation with two variables, replace the variables with the values given and then solve the now variable-free equation. (Remember order of operations, PEMDAS, Parentheses, Exponents, Multiplication/Division, Addition/Subtraction.)
If a = 6, b = 2, c = 9, and d = 7, what is the perimeter of this quadrilateral?
| 24 | |
| 15 | |
| 14 | |
| 25 |
Perimeter is equal to the sum of the four sides:
p = a + b + c + d
p = 6 + 2 + 9 + 7
p = 24
What is 2a4 + 9a4?
| a48 | |
| 11a4 | |
| -7a8 | |
| 11 |
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.
2a4 + 9a4 = 11a4
