will mark brainliest 21 points (08.05, 08.06 MC) Part A:The area of a square is (4x2 − 12x + 9) square units. Determine the length of each side of the square by factoring the area expression completely. Show your work. (5 points) Part B: The area of a rectangle is (16x2 − 9y2) square units. Determine the dimensions of the rectangle by factoring the area expression completely. Show your work. (5 points) (10 points)

Part A: 1.5 square units

Part B: Not enough information to determine ONE solution

Step-by-step explanation:

Part A:

This is an equation which factors to the form (a - b) * (a - b).

So, the factors are

  (2x - 3) * (2x - 3) = 0

  2x - 3 = 0

  2x = 3

  x = 1.5

Part B:

This is an equation which factors to (a + b) * (a - b).

So, the factors are

  (4x - 3y) * (4x + 3y) = 0

There are still 2 variables but only one equation so it can not be solved. There are many solutions to this problem.

length of each side is 2x-3

dimensions are 4x-3y, 4x+3y

Step-by-step explanation:

Part A:

4x2 − 12x + 9

(4x^2 -6x) (-6x + 9)

2x( 2x - 3) -3(2x - 3)

(2x - 3)(2x-3)

length of each side is 2x-3

Part B:

16x^2 − 9y^2

(4x)^2 - (3y)^2

(4x - 3y) (4x+3y)

dimensions are 4x-3y, 4x+3y
