WILL MARK BRAINLEIST!! Each figure is composed of large squares and small squares. The side length of the large square is x. Write an expression for the area of the shaded part of each figure.

Figure A

Figure B

** Please help!!

9514 1404 393

  A. x² -4

  B. 2x² +8

Step-by-step explanation:

The area of a square is the square of the side lengths. That means the area of each large square is x², since it has a side length of x.

__

A. The area of 4 small squares is subtracted from the area of the large square to find the shaded area:

  x² -4×1² = x² -4 . . . area of Figure A

__

B. The area of two small squares is added to the area of two large squares to find the shaded area:

  2x² +2×2² = 2x² +8 . . . area of Figure B
