Answer:
He walks 28 blocks.
Step-by-step explanation:
0,0 to 0,8 is 8 blocks
0,8 to 6,8 is 6 blocks
6,8 to 6,0 is 8 blocks
returning home (6,0 to 0,0) is 6 blocks
8+6+8+6=28 blocks
 
        
             
        
        
        
Answer:The perimeter =12w
Step-by-step explanation:
Let the width represent W and Length represent L
Length= 5 x width
L=5W
W=W
Since perimeter =2(L+w)
Substitute for L=5w
=2(5w+w)
=2(6w)
=12w
 
        
             
        
        
        
Using Pythagoras: 
12^2+5^2= 144+25=169
√169= 13
        
                    
             
        
        
        
Answer:
Step-by-step explanation:
A
y = 7 - x
y = 7 - 2
y = 5
B
y = x^2 - 1
y = (2)^2 - 1
y = 2*2 - 1
y = 4 - 1
y = 3
C
y = x + 14 
I'm going to assume that you mean (x + 14)^3
y = (x + 14)^3
y = (2 + 14)^3
y = 16^3
y = 4096
If you really do mean what it says, then
y = 2 + 14^3
y = 2744 + 2 
y = 2746
