Area = length x width
with a little algebra we can reorganize the equation and solve for length...
A = L x W
A/W = L
So the statement divide the area by the width is TRUE.
Answer:
Step-by-step explanation:
I think you mean 0.5 in:20 mi
2 in × (20 mi)/(0.5 in) = 80 mi
2 inches on the map corresponds to 80 miles.

or 4 + 4 + 4 + 4 + 4 + 4 + 4 + 4 + 4 = 36
Answer:

Step-by-step explanation:
LCD: 10

answer: 
D = sq.root of((x2 - x1)^2 + (y2 - y1)^2)
sq.root of 13 = sq.root of((x - (-2))^2 + (1 - 3)^2)
= sq.root of((x + 2)^2 + (-2)^2)
= sq.root of (x^2 + 4x + 4 + 4)
= sq.root of (x^2 + 4x + 8)
Now if we square both sides:
x^2 + 4x + 8 = 13
x^2 + 4x - 5 = 0
(x + 5)(x - 1) = 0
x = -5 or x = 1
