Answer:
the last side is 30 inches
Step-by-step explanation:
Let the original price of the book be x. If, after a 33% markup on the initial price, the student had to pay 115.00 for it, then we can calculate x as:
(1 + 33%)(x) = 115
1.33x = 115
x = 115/1.33 = 86.47
This means that the bookstore paid $86.47 for the book.
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
.
