Answer:
m∠ACD = 140°
Step-by-step explanation:
You know that 90° is a right angle.
And you know that 180° is no angle.
If m∠B = 60° and m∠A = 80°, all you do is add 60° and 80°.
<u>60 + 80 = 140</u>
17/5 if the mixed number =) hope this helps
Answer:
i think it is d
Step-by-step explanation:
-x-5
- -5x^2 - 3
or
(-x-5) - (-5x^2 - 3)
First, distribute the -. So then it becomes
-x - 5 + 5x^2 + 3
Since you can't add 5x^2 to -x. You can only combine -5 and 3.
Thus it becomes
- x + 5x^2 -2
However, you order in exponents so
5x^2 - x - 2
would be the correct answer.
