Answer:

c. 43

d. 3x² + 5x + 8

Step-by-step explanation:

Part c.

To find the perimeter if x = 2, we need to replace x by 2 on the given expression, so

P = 12x + 19

P = 12(2) + 19

P = 24 + 19

P = 43

So, the perimeter is 43.

Part d.

If a = x², b = 4x + 8, c = 2x², and d = x, the perimeter of the figure will be

P = a + b + c + d

P = x² + (4x + 8) + 2x² + x

P = (x² + 2x²) + (4x + x) + 8

P = 3x² + 5x + 8

So, the perimeter is 3x² + 5x + 8
