Answer:
P = 20
Step-by-step explanation:
Hello!
We can solve this by substituting -4 for t.
<h3>Evaluate</h3>
- P = 3t² + 7t
- P = 3(-4²) + 7(-4)
<u>Remember that any negative number squared is the absolute value of that number squared.</u>
- P = 3(|-16|) - 28
- P = 3(16) - 28
- P = 48 - 28
- P = 20
The final evaluation is 20.
The answer is (2z-3)(z+3)
Answer: 1 1/2 hour or 3/2 half hours
