-x^2+5x-6

Please help me understand how to factor this. Thank you. :)

-(x-3)(x-2)

Step-by-step explanation:

-(x²-5x+6)

-(x²-3x-2x+6)

-{x(x-3)-2(x-3)}

-(x-3)(x-2)

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°
