Step-by-step explanation:
A polynomial is a expression with more than one terms.
The expression with negative exponent is not a polynomial.
Expression in the denominator is also not a polynomial
has two terms without any negative exponent. so it is a polynomial.

Answer:
X = 100
Step-by-step explanation:
- In proportion questions, they want you to multiply one of the sides by a variable, (i usually represent it with K) and then change the proportion sign to an equal.
- This is because proportional means they have a ratio between them, with one side increasing by "k" for each increase in the other side.
- Multiply the left by k, so
- we know that y= 5, for x = 36, so sub this in the equation
- simplify
- re-arrange for k, <u>k = 5*6 = 30</u>
- now we know k, we can create the real equation,
- sub in 3 as y
- <u>x = 100</u>
When simplifying you need to be able to divide both the top and bottom number in the fraction by one of their factors. A number will be fully simplified when they become a prime number or have one as the numerator.
