Answer:
Part A) The polynomial has three terms
Part B) The terms are 
Part C) Is a 2nd degree polynomial
Part D) The name of the polynomial is a 2nd degree trinomial
Step-by-step explanation:
we know that
Polynomials can be classified two different ways - by the number of terms and by their degree.
we have

The polynomial has three terms
The terms are

therefore
The polynomial is a trinomial
The degree of the polynomial is found by looking at the term with the highest exponent on its variable(s).
The term is 
The highest exponent is the 2 so this is a 2nd degree polynomial
therefore
The name of the polynomial is a 2nd degree trinomial
Answer:
Isolate the variable by dividing each side by factors that don't contain the variable.
Inequality Form:

I’m pretty sure it’s D) 160
Answer:
MY=80
Step-by-step explanation:
MX=MY ( since M is the midpoint)
2x+10=3x-5
10+5=3x-2x
15=x
MX+MY=MX
2x+10+3x-5=MY
2(15)+10+3(15)-5=MY
MY=80
