The coefficient of the first term of a polynomial written in standard (descending order) form is called the coefficient.

the coefficient of the first term of a polynomial written in standard form is called the leading coefficient.

for example,

in 6x^3 + 8x^2 + 6x, the first term is 6x^2 and the coefficient of this term is 6.

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°
