If c=sqrt of 5 and d= 2/5, which expression represents an irrational number? a) c^2 b)d^2 c) c+d

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

the answer is d
