X^2+8x=3x i need the answer quick

x = 0 or x = -5

Step-by-step explanation:

Solve for x over the real numbers:

x^2 + 8 x = 3 x

Subtract 3 x from both sides:

x^2 + 5 x = 0

Factor x from the left hand side:

x (x + 5) = 0

Split into two equations:

x = 0 or x + 5 = 0

Subtract 5 from both sides:

 x = 0 or x = -5

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°
