Answer: 0.1 or 10% per inch.
When you have two unit prices for two comparable items, you have to convert one of the prices to the other one.
Answer: 18x^4 - 5x^3 + x^2 - 4
Step-by-step explanation:
We need to add like terms.
-10 and 6 are like terms
-10 + 6 = - 4
-3x^3 and -2^3 are like terms
-3x^3 + -2^3 = -5x^3
There are no other like terms.
18x^4 - 5x^3 + x^2 - 4
Answer C : 3x^2+7xy-2y^2
equivalent to the following expression
Combine like terms
2x^2 + x^2 is 3x^2
4xy+3xy is 7xy
-y^2-y^2 is -2y^2
So expression becomes
Answer C is correct
