Answer:
Speed
Step-by-step explanation:
To find the distance the formula is d=st. Where d is the distance, s is speed, and t is time. So in the equation, 3 must be the speed of the snail.
Expand the left side:
(3x + 2) (5x + 1) = 15x² + 10x + 3x + 2 = 15x² + 13x + 2
Then a = 15 and b = 13, so a - b = 2.
