Answer:

option c

Step-by-step explanation:

a guitar 15% off means that the cost is now 85%

100percent---200dollars\\85percent---x\:dollars\\\\x=\frac{200*85}{100}\\\\x=2*85\\\\x=170

now the 8% of 170 is

100\:percent---170\:dollars\\\\8\:percent---x\:dollars

x=\frac{8*170}{100}\\\\x=\frac{8*17}{10}\\\\x=13.6

so the total cost is

170+13.6

183.6

I dont unsterstand irrational numbers​
elixir [45]

An irrational number cannot be expressed as a ratio between two numbers and it cannot be written as a simple fraction because there is not a finite number of numbers when written as a decimal. Instead, the numbers in the decimal would go on forever, without repeating.

Marizza181 [45]
Let x,y be two different numbers
suppose x^2=y^2
then x^2-y^2=0
which yields (x+y)(x-y)=0
so either x=y or x=-y
In any case, x and y must be the same value
also when a vairable is squared like y=x^2
we must note that there are 2 possible solutions
x=(+/-)sqrt(y)
