Answer

11$r^{3}$+11

Work Step by Step

STEP 1: First, write down the equation. (5$r^{3}$ + 8) + (6$r^{3}$ + 3) STEP 2: In order to add binomials, we combine like terms. First, group the like terms together. (5$r^{3}$ + 6$r^{3}$) + (8 + 3) STEP 3: Then, add the coefficients together to simplify. (11$r^{3}$) + (11) 11$r^{3}$ + 11
