Answer:
A
Step-by-step explanation:
Given
p² + 2p - 8 = 0 ← in standard form
with a = 1, b = 2, c = - 8
Using the quadratic formula to solve for p
p = ( - 2 ± 
/ 2
= ( - 2 ± 
/ 2
= ( - 2 ± 
) / 2
p = 
= 
= - 4
p = 
= 
= 2
Answer:
15%
Step-by-step explanation:
40=100%
20=50%
4=10%
2=5%
10%+5%=15%
4+2=6
So you start by subtracting 3 from 35, which is 32. 32/8 = 4. So three years ago, Tim's son was 4 and Tim was 32. The percentage is about 13%
