Answer:
W=5
Step-by-step explanation:
W=Width=Length + 1
L = Length
Area = Length * Width = 20
Area = L * W = L * (L+1) = 20
Distribute the L:   L^2 + L = 20
Subtract 20 from both sides: L^2 + L -20 = 20-20
Simplify:  L^2+L-20=0
Factor (L-4)(L+5)=0
Solve using the zero property: L-4=0, L=4      L+5=0, L=-5
The two options for length are 4 and -5. Only 4 will work for L since it cannot be negative.   Width is Length + 1 = 5
 
        
             
        
        
        
Answer:
m=2
Step-by-step explanation:
slope is the average rate of change in a specific interval
we can calculate slope in this case with Δy/Δx or (y2-y1)/(x2-x1)
m=(y2-y1)/(x2-x1)
=(-1-7)/(-3-1)
=-8/-4
=2
