Answer:
-x³ + 5y + 3
Step-by-step explanation:
It helps to rewrite the given polynomial according to its degree (exponent), in <u>descending</u> order. Also, for variables without a coefficient, it helps to include "1" with it to make it less confusing when combining like terms.
- x³ + 3y + ( 1 )y + ( 1 )y + 5 + 2 - 4
One way to simplify a polynomial is to combine the like terms if there are any. Two or more terms in a polynomial are like terms if they have the same variable(s) with the same exponent.
- x³ is the only term with an exponent of 3, so we wouldn't have to combine it with other terms. We need to combine the terms with the variable "y," as they have the same degree of 1.
- x³ + 5y + 5 + 2 - 4
Lastly, combine the constants (5 + 2 - 4):
- x³ + 5y + 3

Answer:
28 Students
Step-by-step explanation:
Let's break down all of our variables.
likes strawberry
likes chocolate
7 likes vanilla
First we need to combine the number of students that like strawberry and chocolate.
This then tells us that the 7 kids that like vanilla are the remaining of the class.
Let's use ratio to find out how many students there are in total.
Let x = number of student in Mrs. B's class.
We need to multiply 4 to 7 and x to 1.
So that leave us with:
x = 28
There are 28 students total in Mrs. B's class.
