Answer:
p = 2 or p = - 18
Step-by-step explanation:
given [tex]\frac{|p+8|}{2}[/tex] = 5 ( multiply both sides by 2 )
| p + 8 | = 10
The expression inside the absolute value can be positive or negative
that is p + 8 = ± 10
p + 8 = 10 ⇒ p = 10 - 8 = 2
p + 8 = - 10 ⇒ p = - 10 - 8 = - 18
Answer:
p = 2 p = -18
Step-by-step explanation:
|p+8| over 2 =5
|p+8|
----------- = 5
2
Multiply each side by 2
|p+8|
2*----------- = 5*2
2
|p+8| =10
With absolute values we have a positive and a negative solution
p+8 = 10 and p+8=-10
Subtract 8 from each side
p +8-8 = 10-8 p+8-8 = -10-8
p = 2 p = -18
