Answer:

16 units

Step-by-step explanation:

A/B = 5/4 = 20/p

Find the quotient when x2 + 10x + 21 is divided by x + 7
Alja [10]

Answer:

The quotient is x+3

Step-by-step explanation:

We first use the remainder theorem to determine whether x+7 is divisible by

x^2+10x+21:

(-7)^2+10(-7)+21\\ = 49 - 70+21 = 0

the remainder is zero which means x^2+10x+21 is divisible by x+7.

Now, we could do polynomial long division to find the quotient, but in this case, it turns out that guessing is easier.

x^2+10x+21

is factored as

x^2+10x+21 = (x+7)(x+3)

which means

\dfrac{x^2+10x+21}{x+7} =(x+3)

which means the quotient is x+3.
