x=± () ()

Step-by-step explanation:

Let's solve your equation step-by-step.

−8=−12

Step 1: Add 8 to both sides.

−8+8=−12+8

75x4=−4

Step 2: Divide both sides by 75.

= −

=

Step 3: Take root.

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°
