Answer:
Step-by-step explanation:
When we multiply a polynomial by a specific monomial, all terms in the polynomial get multiplied by the monomial.
So we can do this by term.
Multiplying x by x to the something power will just increase the exponent on the x term by one (since powers are just x multiplied by itself). This means the exponent here will increase by 1, so this becomes 
.
Same logic applies to the second term: 
, raise the exponent by one, 
.
For the third term, if there is no exponent on a term you can assume it's exponent is 1 (so 
in this case - as 
). Again, using the same logic, this turns into 
.
For the last term, when we multiply a constant by a variable, we get a term with a variable and a coefficient - the constant becomes the coefficient and the variable stays the variable. Therefore, 
.
Adding these terms all together gets us 
.
Hope this helped!

Step-by-step explanation:
just took the test
Based on the fact that he added three correct questions, Levi is wrong in assuming that the ratio of correct answers to total answers remained the same.
<h3>Why is Levi wrong?</h3><h3 />
When the total number of variables being compared in a ratio changes, the ratio itself will change.
This means that Levi is wrong in assuming that the ratio of correct answers to total questions will remain the same after he added 3 questions to both measures.
The first ratio of correct answers to questions was:
8 : 10
4 : 5
After three correct answers are added, it becomes:
11 : 13
This is not the same as the first ratio of 4 : 5.

I believe it is 45 feet. Equation: tan(66)=20/x. Change it to 20 tan(66) in a calculator and that is how you get it.
X equals 1/2. I got that answer by taking the root of both sides of the equation
