3/16 is the answer the answer
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)
Answer: 18
Step-by-step explanation: The radius is always half of the diameter, so 36 divided by 2 is 18.
Heck yeah!!!
ok so do 5x3=15 divide by 2(really don't need to do that!)
15x 2=30 or 7.5x4=30
then add 3x3=9 to 30 so 9+30=39
ur answer is 39
hope this helps!!!!
