KengaRu [80]

Answer:

the area of the space he can cover with carpet =  16x⁴ yards²

Step-by-step explanation:

The shape of the square is not shown in this question.

Let assume that the base of the shape of the square is 2x² yards.

and Manny has four of that.

Then side we known the base, we can calculate for the area of the square.

Area of a square = l²

Area of a square = (2x² yards)²

Area of a square = 4x⁴ yards²

However, since Manny has four pieces of that carpet and wants to use them together to carpet a portion of his basement.

Let the pieces of the carpet be carpet A, B, C and D

where; their side is 2x² yards, then their area = 4x⁴ yards²

the area of the space he can cover with carpet =  A+B+C+D

the area of the space he can cover with carpet =  4x⁴ yards² +  4x⁴ yards² +  4x⁴ yards² +  4x⁴ yards²

the area of the space he can cover with carpet =  16x⁴ yards²

The graph crosses the y axis at 7

So y axis is (0,7)

The graph is increasing at first  and reaches (-2,8)  and then start  decreasing

The graph start increasing at x=-10  and goes on increasing till x= -2

then the graph start decreasing at x=-2  and goes in decreasing till x= 10

The graph crosses the y axis at (0,7), increasing from x=-10  to x=-2  and decreasing from x=-2 to x=10

Answer D is correct
