Hello from MrBillDoesMath!
Answer:
sqrt(6)
Discussion:
The triangle, while not indicated, appears to be a right triangle (i.e. has a 90 degree angle). If so, from the Pythagorean theorem,
x^2 + 3^2 = ( sqrt(15) ) ^ 2 =>
x^2 + 9 = 15 => ( subtract 9 from both sides)
x^2 = 15 - 9 = 6 => (take the square root of both sides)
x= sqrt(6)

Step-by-step explanation:
The term 6b represents the original price of loaves of bread and 0.78b represents the amount of discount on 6 loaves of bread.
Step-by-step explanation:
Given,
Sale = 13% off
Number of bread purchased = 6
Original price of loaf of bread = b
The given expression is;
6(b-0.13b)
Expanding the expression;
6b-0.78b
5.22b
Here;
The term 6b represents the original price of loaves of bread and 0.78b represents the amount of discount on 6 loaves of bread.
