Answer:
three
Step-by-step explanation:
One hundred box, two sticks, and three circles.. to spell out 123! (I think)
You can solve all of these by using the distance formula. I have shared it below.
Explanation
Let's first graph the elements:
Using the distance formula we get:

Answer:
-a(a+4)/(16 - a²)
Step-by-step explanation:
a/(a - 4) Multiply by (a + 4)/(a + 4)
= a(a + 4)/[(a – 4)(a + 4)] Multiply the denominatorator terms
= a(a + 4)/(a² - 16) Multiply by -1/(-1)
= -a(a+4)/(-a² + 16) Reorder terms in denominator
= -a(a+4)/(16 - a²)
