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:
9 cm
Step-by-step explanation:
27 / 3 =9 cm
The total periméter is 27 and it has 3 sides so just divide
The bottom left, lies never -6 on x axis and 20 on y axis
Answer:
all the possible values of y - x are 4 and 5
all possible values of x/y = 1
Subtract 3 first so it would be 7x=15
then divide by 7 so x would be approximately 2.14
