Answer:
D
Step-by-step explanation:
Given the quadratic
d = - 16t² + 12t ← subtract d from both sides
- 16t² + 12t - d = 0 ← in standard form
with a = - 16, b = 12, c = - d
Use the quadratic formula to solve for t
t = ( - 12 ± 
) / - 32
= ( - 12 ± 
) / - 32
= ( - 12 ± 
) / - 32
= ( - 12 ± 4
) / - 32
= 
± 
= 
± 
= ± 
→ D
Answer:
25 doughnuts
Step-by-step explanation:
for 15 workers,
the numbers of doughnuts =
5 doughnuts/3 workers × 15 workers
= 75/3 doughnuts
= 25 doughnuts
12x - 18 - 4x -2
12x - 4x = 8x (yours 12x - 4x = 8)
-18 - 2 = -20 (yours -18 -1 = 17)
answer:
8x - 20
The 2nd option is the answer :)!
0.1 0.2 because its only sum of only 0.3
