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:
36 prices
Step-by-step explanation:
Given the following :
Dentist bought 9 bags of prizes for his patients
Each bag had 12 prizes, and prices were divided equally among three boxes: The each box will. Have :
Total number of prices :
Number of bags × number of prices per bag
9 × 12 = 108 prices
Number of boxes in which prices were equally distributed = 3
Hence, each box will have :
Total prices / number of boxes
= 108 / 3
= 36 prices per box
Answer:
x = -9 ; x = 7
Step-by-step explanation:
We have to find two numbers whose product is -63 and whose sum is 2
the two numbers are 9 and -7
(x+9)(x-7) = 0
x = -9
x = 7

Most have only 4 different equations.
For example,
6+8=14
8+6=14
14-6=8
14-8=6
