Is of - 4x + 2? a. 3 b. 4 c. 6 d. 5

D. 5

Step-by-step explanation:

x^5 - 4x + 2

The degree of the polynomial is the degree of the highest term

x^5:  5th

4x: 1st

2: 0

So the degree of the polynomial is degree 5

stops on an even number.

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.
