By using what we know about polynomials, we will see that the missing side measures 8x - 1

How to get the perimeter of a triangle?

The perimeter of a triangle is just the sum of its 3 sides, in the image the two known sides are: 3x - 5 and x + 2, and the missing side measures p(x).

Then we will have that the perimeter is the sum of these 3 lengths:

13x - 4  = 3x - 5 + 2x + 2 + p(x)

13x - 4 = 5x - 3 + p(x)

Now we can assume that p(x) is also a linear polynomial, so:

p(x) = a*x + b

Then we have:

13x - 4 = 5x - 3 + a*x + b

This means that:

5 + a = 13

-3 + b = -4

Solving these we get:

a = 13 - 5 = 8

b = -4 + 3 = -1

This means that the missing length is:

p(x) = 8x - 1
