Answer:
= (x+4) (x-7)
Step-by-step explanation:
x²-3x -28
Product = -28
Sum = -3
numbers = -7 and 4
Thus;
x²- 3x -28 ; replacing -3x with -7x and 4x
x²-7x +4x -28
x(x-7) + 4(x-7)
<u>= (x+4) (x-7) </u>

Hello! Remember you have to write complete questions in order to get good and exact answers. Here I'll help you assuming some things. First of all, for a two dimensional shape, the perimeter is defined as the distance around it. Suppose we have a rectangle whose dimensions are:

So in this context:
Correct option is D. 10x - 20
I Would Say A Is The Correct One
