Perimeter = (2x -3y) + (x² + 7) + (2x + y)
Perimeter = 2x -3y + x² + 7 + 2x + y
Perimeter = x² + 4x - 2y + 7
------------------------------------
Answer: x² + 4x - 2y + 7

Answer:
B: -14
Step-by-step explanation:
given that f(x) = -2x - 13,
we can find the value of f(-3) by simply plugging in -3 for x
f(-3) = -2(-3) - 13
f(-3) = -7
Because we are dealing with the expression f(-3) - 7, we still have one more step. Let's plug in -7 for f(-3)
- 7 - 7 = -14
Therefore, f(-3) - 7 will give us B: -14
