A car's rear windshield wiper rotates 120°. The total length of the wiper mechanism is 21 inches and the length of the wiper blade is 11 inches. Find the area wiped by the wiper blade. (Round your answer to one decimal place.)

answer: r there any options?

step-by-step explanation:

3. (5x + 1) - (-10x + 6)

simplify the answer choice. combine like terms. remember to distribute the negative to the terms inside the second parenthesis. also remember that two negatives = one positive, and one of each sign = negative.

- (-10x + 6) = + 10x - 6

simplify. combine like terms:

5x + 1 + 10x - 6

5x + 10x + 1 - 6

15x - 5

∴ it is your answer

x = 3 ± √(5+y)
