a) x(x - 2)

b) 6x(x + 2)

c) 3x(x^2-3)

d)  (2x)(2x)(1+7x)

Step-by-step explanation:

168

step-by-step explanation:

first off, we know that he drove 3.5 hours at a rate of 48 mph.

knowing that, we want to see how many miles he drove all-together.

in this case, we can just multiply 48 by 3.5.

48 * 3.5 = 168
