Answer:
after 2 seconds
Step-by-step explanation:
We want to find t such that h = 0.
0 = -16t² +8t +48
0 = 2t² -t -6 . . . . . . . divide by -8
0 = (t -2)(2t +3) . . . . factor
The only positive solution is t = 2, which makes the first factor zero.
Stella will land in the water at t = 2 seconds.
It has to be d because the rest equal to 24y-&

Answer:
(3x + 1) (2x + 1)
Step-by-step explanation:
ax² + bx + c can be factored using the AC method:
1. Multiply a and c.
2. Find factors of ac that add up to b.
3. Divide each factor by a; reduce the fractions.
4. The denominator is the coefficient, the numerator is the constant.
6x² + 5x + 1
1. ac = 6 × 1 = 6
2. Factors of 6 that add up to 5: 2 and 3.
3. 2/6 = 1/3, and 3/6 = 1/2
4. The factors are 3x+1 and 2x+1.
6x² + 5x + 1 = (3x + 1) (2x + 1)
