Part A: 3x + 15 = 5x - 25
Part B: x = 20
Putting equation
0 = -16t² + 36t + 4
<span>0 = -8t² + 18t + 2 ← Complete the square to solve </span>
<span>-8(t² - 9t/2) = -2 </span>
<span>8(t² - 9t/4 + 81/64) = 2 + 81/8 </span>
<span>8(t - 9/8)² = 97/8 </span>
<span>(t - 9/8)² = 97/64 </span>
<span>t -</span><span> (t = 0) </span>
<span> (h = 0) at: </span>
<span>t = (9 + √97)/8 ≅ 2.356 seconds
hope it helps</span>

Answer:
June will drive 275 miles in 5 hours.
Step-by-step explanation:
- 176/3.2 = x/5
- 3.2x = 176(5)
- 3.2x = 880
- x = 880/3.2
- x = 275
- June will drive 275 miles in 5 hours.
