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.

step-by-step explanation:

answer: (c) m∠qpo + (2x + 16)° = 180°

step-by-step explanation:

the opposite angles of a quadrilateral are supplementary.

so, ∠o + ∠q = 180°   and   ∠p + ∠r = 180°

since ∠r = 2x + 16°, we can use substitution as follows:

∠p + ∠r = 180°

∠p + (2x + 16)° = 180°
