Tell whether a triangle can have sides with the given lengths. Explain, why or why not.
3x + 2, x?, and 2x when x = 4

for

Step-by-step explanation:

Given

Shape: Triangle

Dimension: 3x + 2, x^2 and 2x

Required

Determine if it has equal sides

To do this, we simply substitute 4 for x in the given dimensions

3x + 2

x^2

2x

for

reduce the friction between its moving parts
