Answer:

2- Supplementary

Step-by-step explanation:

Since both Angles A and C lie on the same line, they are supplementary. Supplementary angles add up to 180°.

Congruent angles are equal. Here, if Angles A and C are congruent, they would be 180° ÷ 2 = 90° each, so congruent is the wrong answer.

What is the value of the following expression? 2w - 6, when w = 6

lara31 [8.8K]

Answer:

The answer is 6.

Step-by-step explanation:

Since w = 6 you would input the 6 where the w value is. Your equation should look like this: 2(6)-6

First you multiple the 2 x 6 which equals 12. After you minus 12-6 which equals 6. Therefore your answer is 6.

Add: <br> 3x+9+8x + 12<br> 2x + 6+x² + 6x + 9

Oxana [17]

I'll treat these like they're two seperate problems because how you set it up they're not together. If it's one whole problem please tell me and I'll solve it that way. :-)

First one: 3x+9+8x + 12

Collect like terms and simplify

(3x+8x)+(9+12)

11x+21

Second one: 2x + 6+x² + 6x + 9

Collect like terms and simplify

$(2x+6x)+(6+9)+x^{2}$

8x+15+ $x^{2}$

Hope this helps you, have a BLESSED and wonderful day, as well as a safe one!
