someone please help with this question for brainliest !!!!:)

Answers

Answer:

d)

Step-by-step explanation:

the polynomial remainder theorem states that the remainder of the division of a polynomial f(x) by a linear polynomial x-r is equal to f(r). In particular, x-r is a divisor (that means a factor) of f(x), if and only if f(r)=0.

our r here is -1 to get x + 1.

f(-1) = 2×(-1)³ + 5×(-1)² - -1 - 6 = -2 + 5 + 1 - 6 = -2

the remainder is -2.

and since the remainder is <> 0, the binomial cannot be a factor.

4.8/(1 7/9)=(1.2b):6 2/3 I will mark as brainliest, i swear

Answers

Answer:

b = 15

Step-by-step explanation:

Answer:

b = 15

Step-by-step explanation:

Solve for b:

4.8/ 1 7/9 = 1.2b/6 2/3

Cross multiply:

6 2/3 * 4.8 = 1.2b * 1 7/9

6 * 3 + 2/3 * 4.8 = 1.2b * 9 + 7/9

20/3 * 48/10 = 12b/10 * 16/9

20 * 4 = b * 16/3

5 = b * 1/3

b = 5 * 3

b = 15
