Answer: The radius is 8
Step-by-step explanation:
There are 96 possible combinations.
The fundamental counting principle states that the number of total options is given by multiplying the number of possibilities for each option, or
Total choices = choices x choices x ...
4*3*8 = 96
If it’s either nonincreasing or nonincressing
Use the folumla AB^2 = BD * (CD + BD)
fill in the known numbers:
AB^2 = 12 x (15 +12)
AB^2 = 12 x 27
AB^2 = 324
AB = SQRT(324)
AB = 18
When you multiply you just multiply the numerators and the denominators.
when you divide, you flip the second fraction over and then multiply the fraction.
when you add fractions you multiply across then add the two fractions.
