Identify the coefficients for the following quadratic equation. 2x squared minus 9x equals negative 4

a =

b=

c=

2

Step-by-step explanation:

the number before the x² is regarded as the identity element

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°
