x+9/x+1
Step-by-step explanation:
Since the denominator is the same, just add the numerator while keeping the denominator the same.
because the cost is $0.35 or higher
the cheapest song is $0.35
Equilateral triangle means all sides have equal length.
Perimeter
As a sum: (x-4.5)+(x-4.5)+(x-4.5)
As a product: 3 * (x-4.5)
They are equivalent because 3 times a number is just the sum of three of the number.
