Answer: Option 'c' is correct.

Step-by-step explanation:

Let the number of children be 'c'.

According to question,

"There are 9 more children than parents in a room.

Let the number of parents would be 'p'.

According to question, it becomes,

c-p=9\\\\c-9=p

As there are total 25 people in the room = 25

So, it becomes,

c+p=25\\\\c+c-9=25\\\\2c-9=25\\\\2c=34\\\\c=17

Hence, there are 17 children and 17-9 = 8 parents.

Therefore, option 'c' is correct.

Use the Remainder Theorem to find the remainder: (16x^4 – 8x^3 – 4x + 1) ÷ (2x + 1)
vodka [1.7K]

Answer:

5

Step-by-step explanation:

This illustrates the Remainder Theorem. If a polynomial f(x) is divided by x−a , the remainder is the constant f(a) , and f(x)=q(x)⋅(x−a)+f(a) , where q(x) is a polynomial with degree one less than the degree of f(x) . Synthetic division is a simpler process for dividing a polynomial by a binomial.
