Dahlia is simplifying (3 t) Superscript 4 using these steps:

(3 t) Superscript 4 = 3 t times 3 t times 3 t times 3 t = 3 times 3 times 3 times 3 times t times t times t times t

Although Dahlia is correct so far, which step could she have used instead to simplify the expression (3 t) Superscript 4?
A. (3 t) Superscript 4 = 3 t Superscript 4
B. 3 Superscript 4 Baseline t = 81 t
C. 4 (3 t) = 12 t
D. 3 Superscript 4 Baseline t Superscript 4 Baseline = 81 t Superscript 4

in problems involving proportions, we can use cross products to test whether two ratios are equal and form a proportion. to find the cross products of a proportion, we multiply the outer terms, called the extremes, and the middle terms, called the means.

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
