they are giving you the answer AB=AC, so what that means is that the angles are congruent to each other so if angle AC=15 and angle DC=5 all the angles will be the same.
Hopes this helps:
Answer:
12 1/3
∛(1/8 - <em>x</em>) = -1/2
Take the 3rd power of both sides and solve:
(∛(1/8 - <em>x</em>))³ = (-1/2)³
1/8 - <em>x</em> = -1/8
2/8 = <em>x</em>
<em>x</em> = 1/4
1/12 + 5/12 + 1/4 + 1/4 = 6/12 + 2/4 = 6/12 + 6/12 = 12/12 = 1
Yes, they did.
Answer:
0.25 Converges
Step-by-step explanation:
First, we need to expand our series so that we get the following:

We can then use the series ratio test on each term. (L < 1 = absolutely convergent)

=
⇒ converges


⇒ converges
converges + converges
= converges
~Hope this helps! Once again, sorry if my explanation is a bit confusing~
