Answer:

Step-by-step explanation:
We can use the Polynomial Remainder Theorem. It states that if we divide a polynomial P(x) by a <em>binomial</em> in the form (x - a), then our remainder will be P(a).
We are dividing:

So, a polynomial by a binomial factor.
Our factor is (x + k) or (x - (-k)). Using the form (x - a), our a = -k.
We want our remainder to be 3. So, P(a)=P(-k)=3.
Therefore:

Simplify:

Solve for <em>k</em>. Subtract 3 from both sides:

Factor:

Zero Product Property:

Solve:

So, either of the two expressions:

Will yield 3 as the remainder.
Answer:
The teacher can hand out pizza to 8 students.
Step-by-step explanation:
To find how many slices of pizza the teacher can hand out , you can divide 7 by 7/8 and round down the nearest whole number.
7 ÷ 7/8 = 8
8 is already a whole number. No need to round down.
The teacher can hand out pizza to 8 students.
