Find (12x−3)+(16x+1) .

28x-2

Step-by-step explanation:

First, you get rid of the parentheses. Since the symbol is +, nothing really changes: 12x - 3 + 16x +1

Then, you combine like terms to get your 28x-2

28x−2

Step-by-step explanation:

Combine 12x and 16x to get 28x.

28x−3+1

Add −3 and 1 to get −2.

28x−2

28x−2

Factor out 2.

2(14x−1)

hello :

by applying the distributive property :

6 × 4.3 = 6 × ( 4 + 0.3 )

            =   (6 ×   4) + (6 ×   0.3)

            = 24 + 1.8

6 × 4.3 = 25.8

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°
