Best ResponseYou've already chosen the best response.0so, area = (8 feet + x feet / 2) * 10

Best ResponseYou've already chosen the best response.0Solve for x: 65 = 5 (8+x) Divide both sides by a constant to simplify the equation. Divide both sides of 65 = 5 (8+x) by 5: 8+x = 65/5 Use long division to simplify 65/5. 5  1  3  6  5   5   1  5   1  5   0: 8+x = 13 Isolate terms with x to the left hand side. Subtract 8 from both sides: x+(88) = 138 Look for two terms that sum to zero. 88 = 0: x = 138 Evaluate 138. 138 = 5: Answer: x = 5
