Answer - 3.2 hours
because 4.48 miles divided by 1.4 mph equals 3.2
To solve a Linear equation we need to find the slope:
-4-1 / -2-8 =1/2
now that we have the slope we can find our x and y
y-1=1/2(x-8)
y=x/2-3

+ 3x + 5
-

+ 6x + 5
-----------------------------------------
4x - 3 + 0
The answer is 12 including both sides and angles.
When you cut a square piece of paper from one point to the opposite point it should make two triangles.
Thus each triangle has 3 sides and 3 angles so two triangles has 6 angles and 6 sides
So 12, sides and angles added together.
