Simplify the following polynomial expression (3x^2-x-7)-(5x^2-4x-2)+(x+3)(x+2)

The polynomial simplifies to an expression that is a (constant, quadratic, linear) ( binomial, monomial, trinominal) with a degree of (0, 2, 1).

I think the degree is 2. The type is monomial and the answer is -x^2+8x+1. I don't know about constant, quadratic, or linear... Please Help.

I know simplified it is  -x^2 + 8x + 1

The degree of the simplified expression is 2.

It is a monomial

I am almost positive it is constant.

Hope this helped

:D

Ps. Sorry if anything is incorrect, math is my worst subject but I am pretty sure everything is correct.

115 minutes

Step-by-step explanation:

Set you problem 2/23 = 10/x

X represents the number of minutes you are trying to figure out. Cross multiply to get 2x=230. Decide both sides by 2 to get x=115
