Apply the distributive property to factor out the greatest common factor.
9+15=

if you need to no what 9+15 is it is 24

Step-by-step explanation:

get a pis of paper and draw 15 dots and then you add 9 more dots and you have 24

3( 3+5)

Step-by-step explanation:

9 +15

Rewriting 9 as 3*3  and 15 * 3*5

3*3 + 3*5

Factor out 3

3( 3+5)S

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°
