Please help I will give brainliest to whoever gets it correct first!

While this may look like it's a lot to keep track of, its not too bad. We have 7 copies of (-8) in total. The 7 copies due to the exponent of 7. Nice work on getting the correct answer for the second part.

A further detailed breakdown:

(-8)^3 is the same as (-8)(-8)(-8) so we have three copies here

(-8)^4 is the same as (-8)(-8)(-8)(-8) and we have four copies

Overall, we have 3+4 = 7 copies total.

answer: the answer to your question is parallel

b. 1.25 hr

step-by-step explanation:

if you have a constant speed of 60 mph, then you have a ratio between 60 mi. to 1 hr. dividing both sides by 60 we get the ratio

1 mi. to

then mult. both sides by 75 we get the ratio

75 mi. to

simplifying we get

75 mi. to

or 1.25 hr.
