Question

Function p gives the perimeter of an equilateral triangle of side length s. It is represented by the equation p(s)=3x

a. What does P(s)=60 mean in this situation?

b. Find a value of s to make the equation P(s) = 60 true.

Answer 1

A) p(s) means that the perimeter of the triangle is 60 units.

B) A value to make the equation true is s = 20

Explanation:

In the equation p(s) = 60, 60 represents the perimeter of the equilateral triangle.

To find a value of s that makes the equation p(s) = 60 true, plug in 60 as p(s) and solve for s.

p(s) = 3s

60 = 3s

20 = s

So, s = 20 will make the equation true
