Multiply the polynomials. (5x2 + 2x + 8)(7x – 6) a. 35x3 – 16x2 – 44x – 48 b. 35x3 – 14x2 + 44x – 48 c. 35x3 – 16x2 + 44x + 48 d. 35x3 – 16x2 + 44x – 48

D) 35x³ - 16x² + 44x - 48

Step-by-step explanation:

(5x2 + 2x + 8)(7x – 6) = (5x2 + 2x + 8)* 7x + (5x2 + 2x + 8)*(– 6)

= (5x2*7x + 2x*7x + 8*7x) + (5x2*(-6) + 2x*(-6) + 8*(-6) )

=35x³ + 14x² + 56x - 30x² - 12x - 48

= 35x³ - 16x² + 44x - 48

the answer is: the length is 5/6 yards.
