The first side of a triangle measures 4 in. less than the second side, the third side is 3 in. more than the first side, and the perimeter is 15 in. how long is the third side?

Start by representing the lengths of the three sides of your triangle:

first side:  x-4 (inches)
second side:  x (inches)
third side:  (x-4) + 3 (inches)

Add these three quantities up to obtain a formula for the perimeter, and set your sum equal to the given perimeter (15 inches):

x-4  +  x  +  x-4  -3  =  15

3x-11=15
3x=26
x=26/3

Thus, the length of the 2nd side is 26/3; that of the first side is 26/3-4, or 14/3; and that of the third side is 14/3+3, or 23/3 (all measurements in inches).

There are two bc a studen that equals to 2

C. because 6÷3=2 so 3 is half of six so 3/6
