Answer:

4(2x-y) (2x+y)

Step-by-step explanation:

The area of the picture is 2y*2y = 4y^2

The area of the picture and the frame is 4x*4x = 16x^2

The area of the frame is The area of the picture and the frame minus The area of the picture

The area of the frame = 16x^2- 4y^2

Factor out a 4

4(4x^2 -y^2)

This is the difference of squares

a^2 – b^2 = (a + b)(a – b)

a^2 = 4x^2 so a=2x

b^2 = y^2 so b=y

4(4x^2 -y^2) = 4(2x-y) (2x+y)

Answer:

Part A: 100%
Part B: 50%

Step-by-step explanation:

The difference between 10 and 5 is 5

5 is 100% of 5, so 10 is 100% greater than 5 (part A)

5/5 = 1 = 100%

5 is 50% of 10, so 5 is 50% less than 10 (part B)

5/10 = 1/2 = 50%

Part A is 100%, and Part B is 50%

The answer is a decreasing exponential function because the percentage of change is constant. You can obtain this answer by looking at the amount of decrease each time and dividing it by the higher value. If you do this for each step, you'll see that there is a 12% decrease for each year.
