To do this easily, we will use the Factor and Remainder Theorem. When a polynomial is divided by a binomial, equate the binomial to zero to get the value of x. Then, substitute this x to the polynomial. Whatever the answer is, is the remainder.

x - 3 = 0
x = 3

x^3 - 6x - 9x +3
x^3 -6(3) - 9(3) + 3 = -15

Take its absolute value. The remainder would be 15.

WILL AWARD BRAINLIEST (Find the measure of the complement and supplement)
melisa1 [442]

Answer:

The complement is 53  and the supplement is 143

Step-by-step explanation:

Two complementary angles add to 90

PQR and x = 90

37+x = 90

Subtract 37 from each side

37-37 +x =90-37

x = 53

The complement is 53


Two supplementary angles add to 180 degrees

PQR and x = 180

37+x = 180

Subtract 37 from each side

37-37 +x= 180-37

x = 143

The supplement is 143
