In order to add or subtract fractions, they must have the
same denominator. You need to change both of these
fractions to have the same denominator ... without changing
their values, of course.
The smallest common denominator for these fractions is 20 .
3/4 is the same amount as 15/20 .
3/5 is the same amount as 12/20 .
Now that they have the same denominator, you can do
the subtraction.
The perimeter of the triangle is: 4x+9
Step-by-step explanation:
Perimeter is the measurement of boundary of any closed figure.
Given
s1 = x+4
s2 = x+8
s3 = 2x-3
So, the perimeter will be the sum of all three sides

Hence,
The perimeter of the triangle is: 4x+9
