What is the are of the shaded region. The inner square is a width of x and a length of x+7. The outer square is a length of 4x and a width of 2x + 1.

7x²-3x

Step-by-step explanation:

What is the are of the shaded region. The inner square is a width of x and a length of x+7. The outer square is a length of 4x and a width of 2x + 1.

Area of a square = Length * Length

Area of the inner square = x (x+7)

Area of the inner square = x²+7x

Area of the outer square = 4x(2x+1)

Area of the outer square = 8x²+4x

Area of the shaded region = Area of outer square - Area of inner square

Area of the shaded region = (8x²+4x)-(x²+7x)

Area of the shaded region = 8x²+4x-x²-7x

Area of the shaded region = 7x²-3x

This gives the area of the shaded region

pls ask

i think it might be a but you might want a second opinion
