The solutions to f(x) = 64 is x = 7 and x = –7.
Solution: 
Given data:
 – – – – (1)
 – – – – (2)
To find the solutions to f(x) = 64.
Equate equation (1) and (2), we get

Subtract 15 from both sides of the equation.



Taking square root on both sides of the equation, we get
x = ±7
The solutions to f(x) = 64 is x = 7 and x = –7.
 
        
             
        
        
        
Answer:
2(3x+2) is your answer because you factor out 2. The number 2 is a factor of both 6 and 4 (2*3=6 and 2*2=4).
 
        
             
        
        
        
parallel: g(x) = -5/3x + 1 
perpendicular: h(x) = 3/5x - 5
neither: j(x) = 2x + 3
 
        
             
        
        
        
The length of PN is 2.63 feet
<u>Explanation:</u>
<u />
Given:
∠P=90°, 
∠O=17°,
OP = 8.6 feet
PN = ?
The given triangle is a right angle triangle as one angle is 90°
We know:


Therefore, the length of PN is 2.63 feet
