Iam hoping someone could kindly show the step by step instruction to solve this equation. i have tried to solve it many times but it is still not clear, could someone show the steps 2(8r^2+r)-4r

30r

Step-by-step explanation:

2(8r2+r)-4r

2(17r)-4r

34r-4r

30r

16r^2-2r

Step-by-step explanation:

2(8r^2+r)-4r

(16r^2 +2r)-4r               Distribute the 2

16r^2+(2r-4r)                Regroup like terms

16r^2-2r

Hope this helps!

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°
