Question

the perimeter of an equilateral triangle is 63 inches . if the lenght of each side is (4x+3),find the value of x write an equation to represent this situation what is the value of x

Answer 1

4.5

Step-by-step explanation:

The perimeter of a triangle can be found by adding the lengths of the sides of the triangle together.

So if we're given the perimeter of the triangle to be 63 inches and the length of each side to be (4x + 3), we can find the value of x as shown below;

`\begin{gathered} 63=(4x+3)+(4x+3)+(4x+3) \\ 63=3(4x+3) \\ (63)/(3)=4x+3 \\ 21=4x+3 \\ 18=4x \\ x=(18)/(4)=4.5 \end{gathered}`
