Is it a multiple choice question
Answer:
D as likely as not.
Step-by-step explanation:
......
Working out the expression 7(3ˣ) is first to calculate the value of 3ˣ then multiply the answer to 7.
For example, let x = 2
Then 7(3ˣ) = 7(3²) = 7 × 9 = 63
With the same value of x = 2, calculating 21ˣ = 21² = 441, which isn't the same answer with the expression 7(3ˣ)
Answer:273
Step-by-step explanation:
52 x 5.25 = 273 miles
15 minutes is 1/4 of an hour so it is .25 so you multiply 52 times 5.25 to find your answer.
