Which polynomial represents the area of the rectangle? (pic shown below) a. 4x^2+2x-6 b.4x^2-2x-6 c.4x^2-6

The formula of an area of a rectangle:

w - width

l - length

Therefore we have:

A = (4x - 6)(x + 1)

use distributive property (a + b)(c + d) = ac + ad + bc + bd

A = (4x)(x) + (4x)(1) + (-6)(x) + (-6)(1) = 4x² + 4x - 6x - 6

4/6 = 2/3

so it should take 3/3 hours per man. so 9 hours is the answer 3*3 =9
