Answer:
7.3
Step-by-step explanation:
For this question, you must use the distance formula. The distance formula is based around Pythagorean Theorem, so you will see some similarities.
Distance = 
X2 is 7 (X coordinate of school)
X1 is 5 (X coordinate of friend's house)
7 - 5 = 2
2^2 = 4
Y2 is 7 (Y coordinate of school)
Y1 is 0 (Y coordinate of friend's house)
7 - 0 = 7
7^2 = 49
4 + 49 = 53
 = 7.2801...
 = 7.2801...
<em>Round to the nearest tenth...</em>
<em>7.3</em>
 
        
                    
             
        
        
        
Equation is
x-6=8
x=8+6
x=14
X equal to 14
