Answer:

P = 20

Step-by-step explanation:

Hello!

We can solve this by substituting -4 for t.

Evaluate

  • P = 3t² + 7t
  • P = 3(-4²) + 7(-4)

Remember that any negative number squared is the absolute value of that number squared.

  • P = 3(|-16|)  - 28
  • P = 3(16) - 28
  • P = 48 - 28
  • P = 20

The final evaluation is 20.
