Question

The length, width and height of a rectangular box are represented by 2x, 4x+1 and 5x-6 respectively. When the volume is expressed as a polynomial in standard from, what is the coefficient of the 2nd term?

Answer 1

the coefficient of the 2nd term: - 38

Explanation:

V = 2x (4x + 1) (5x - 6)

=(8x² + 2x) (5x - 6)

= 40x³ - 38 x² - 12x
