Answer:
Step-by-step explanation:
1. none
because of 12 is not divisible by five
<span>here are the answer choices
m∠ABC=32°
m∠ABC=64°
m∠ABC=90°
m∠ABC=128°
</span>∠ ABC<span> is less than 90</span>° so the 3rd and 4th option is out.
The most likely answer is 64°. m∠ABC = 64°
32° x 2 = 64°
Answer:
A
Step-by-step explanation:
We are given two functions:

And we want to find:

Thus:

We can factor the denominator of the first term:

In order to add the two terms, we must have a common denominator. To achieve this, we can multiply to second term by (x - 4). Therefore:

Multiply:

Combine:

Simplify:

We can expand the denominator:

Therefore, our answer is A.
