Question

Find the sum: (4r^3-r) + (7r^3+8r-3) +(8r+6).

Answer 1

To find the sum of the given expressions, combine like terms by combining the coefficients of the terms with the same variable and exponent. The sum of the expressions is 11r^3 + 7r + 3.

Step-by-step explanation:

To find the sum of the given expressions, you need to combine like terms. Like terms have the same variable and exponent.

First, combine the coefficients of the terms with 'r^3' and 'r' respectively:

(4r^3-r) + (7r^3+8r-3) +(8r+6) = 11r^3 + 7r + 3

So the sum of the expressions is 11r^3 + 7r + 3.
