You can use this formula to find the perimeter of a triange, which is P=a+b+c.P=a+b+c=(2x+5)+(x+8)+(7x)=2x+5+x+8+7x=(2x+x+7x)+(5+8)=10x+13

When rates are expressed as a quantity of 1, such as 2 feet per second or 5 miles per hour, they are called unit rates. if you have a multiple-unit rate such as 120 students for every 3 buses, and want to find the single-unit rate, write a ratio equal to the multiple-unit rate with 1 as the second term.
