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

seems like d

step-by-step explanation:

there is a formula i can give you:

it is r^2*n*sin(360/n) divided by 2 where r represents the "radius" and n is the number of sides.

plug them in:

(10sqrt(3))^2*6*sin(360/6) divided by 2

100*3*6*sin(60) divided by 2

900*sin(60)

900*sqrt(3)/2

450*sqrt(3)

approx is 779.4 cm^2
