6 rap 3 pop take 13-4 which is 9. 6+3=9
The sum of the first n natural numbers and 0=
n*(n+1)/2
The rule for quotients of similar bases with different exponents is:
(a^c)/(a^b)=a^(c-b) in this case:
15^18/(15^3)=15^15
The answer to this is x = 2
The measure of the intercepted arc (a) is twice the measure of the inscribed angle intercepting it (b or 25°). The measures of the inscribed angles are all the same: b = 25°.
The appropriate choice is D. 25
