it is a 3-4-5 right triangle. because it's side lengths (6-8-10 are multiples of 3-4-5) and it has a right angle (90 degrees)
5
1.25 hours = 75 miles = 1/4 of 60 is 15 (of the 1.25)
75/15 (miles per gallon)
What two numbers are able to add up to -8 from multiples of 16?
-4 x -4 = 16
-4 + (-4) = -8
Therefore the factors would be
(x-4)(x-4) or (x-4)^2
