-6(a+8) how do I simplify ?
Answers
Answer:
-6a-48
Step-by-step explanation:
distribute
Use the Distributive Property:
You "distribute" -6 into the equation by multiplying it by each number in the parentheses.
-6(a+8) 1) multiply -6 by a, which equals -6a 2) multiply -6 by 8, which equals -48
Your equation should be -6a-48
From there, it can be seen that you can divide -6 from each number in the equation. -6a/-6 just leaves you with a -48/-6 gives you 8
a-8
Look at picture above. I already did some work, so....

Hi! Like you wrote down, a supplementary angle is when the two angles equal 180 degrees when added together. You can inference that angle B will be 142 degrees (A+B=180, 38+B=180, B=142). Therefore, it cannot be anything less or more than 142 if you want it to be a supplementary angle. The answer is D, which shows that the answer is 142 and nothing more or less.
