Maurice has completed 72 pages of the research paper he is writing. That is 90% of the required length of the paper. What is the
2 answers:
Answer:
80
Step-by-step explanation:
When we first look at this, it generally says "90% of what number is 72?" so that's what we can do.
We can change 90% into a decimal, and put in x, which is what our answer will be!
We can multiply both sides of this equation by 100, and then divide by 90. After all of this, we have
, which is 80.

Answer:
Step-by-step explanation:
<em>The </em><em>Remainder Theorem</em><em> states that when you divide a polynomial by a linear factor
, where
is a constant, the remainder is
evaluated at
</em>
<em>Moreover, according to the </em><em>Factor Theorem</em><em>, an extension of the Remainder Theorem, if the remainder of the function is </em><em>0</em><em> when evaluated at
, then
is said to be a factor of the polynomial
</em>
Given the 2 theorems above, it follows that if is a factor of
, then the remainder is equal to 0 when
is evaluated at
Which means
Third answer choice is correct.
