Identify each function that has a remainder of -3 when divided x+6

a) x^5 + 2x^2 - 30x + 30
b) x^4 + 4x^3 - 21x^2 - 53x + 12
c) x^3 - 10x^2 - 7
d) x^4 + 6x^3 - 10x - 63

D

Step-by-step explanation:

According to remainder theorem, you can know the remainder of these polynomials if you plug in x = -6 into them.

So we will plug in -6 into x of all the polynomials ( A through D) and see which one equals -3.

For A:

For B:

For C:

For D:

The only function that has a remainder of -3 when divided by x + 6 is the fourth one, answer choice D.

b.) 160 miles on a 5 gallons car

step-by-step explanation:

240/10=24 miles/gallon

160/5=32 miles/gallon

30/1=30 miles/gallon

168/6= 28 miles/gallon

32 miles/gallon is the most amount, so this is the best.
