The area of a rectangle can be represented by the expression x2 + 4x – 12. the width can be represented by the expression x – 2. which expression represents the length? 1) x-2(x^2+4x-12) 2) x^2+4x-12/x-2 3) x-2/x^2+4x-12

2) x^2+4x-12/x-2

Step-by-step explanation:

We are given the area and width of the rectangle, and left to find the length. Normally, we multiply length by the width to get the area. In order to find the length, we must do the inverse of what is usually done; we must divide the area by the width which would give us the length. This is how you get the expression:

x^2+4x-12/x-2

b) k’(6, 4); l’(3, 3)

step-by-step explanation:

a 270° clockwise rotation maps every point (x, y) to (y, -x). (it negates the x-coordinate and then switches it and the y-coordinate.)

this means the endpoints of the side congruent to kl, k' and l', would be mapped as:

k'(-4, 6)→(6, 4)

l'(-3, 3)→(3, 3)
