Answer:
Sandra's speed was consistent and persistent she proved it by lining up the segments she placed on the graph and at what time as well.
Multiplying by 0.1 is the same as dividing by 10, as 0.1 = 1/10
So, 37.4x 0.1 = 37.4/10 = 3.74
4x^2-8=136 subtract 136 from both sides
4x^2-144...this is a difference of perfect squares so
(2x+12)(2x-12)
x=±6 or as they put it:
{-6, 6}
