Question

PLZ HELP!!!!!

The perimeter of a square is equal to the perimeter of an equilateral triangle. The length of a side of the square is given by x, and the length of a side of the equilateral triangle is given by x + 1. Which equation can be used to find the value of x?
x = 3 (x + 1)
3 x = 4 (x + 1)
4 x = 3 (x + 1)
x = x + 1

Answer 1

Answer:

4x=3(x+1)

Step-by-step explanation:

Perimeter of the square with side length x is 4x

Perimeter of the triangle with side length x+1 is

3*(x+1)

Given, both are equal,

4x = 3(x+1)

Answer 2

4 x= 3 (x +1) just did the test lol
