<u>Answer:</u>

  • The value of x is 6.

<u>Step-by-step explanation:</u>

<u>We know that:</u>

  • Perimeter of triangle = 3(4x - 3) = 63 in.

<u>Work:</u>

  • 3(4x - 3) = 63 in.
  • => 12x - 9 = 63 in.
  • => 12x = 72 in.
  • => x = 72/12
  • => x = 6

Hence, <u>the value of x is 6.</u>

Hoped this helped.

Answer:

The value of x is <u>6</u>.

Step-by-step explanation:

<u>Question</u> :

The perimeter of an equilateral triangle is 63 inches. If the length lf each side is (4x - 3), find the value of x.

\begin{gathered}\end{gathered}

<u>Solution</u> :

As we know that the formula of perimeter of equilateral triangle is 3a.

Now, according to the question :

\begin{gathered}\longrightarrow\sf{Perimeter = 3a}\end{gathered}

\begin{gathered}\longrightarrow\sf{63 = 3(4x - 3)}\end{gathered}

\begin{gathered}\longrightarrow\sf{63 = (4x \times 3 - 3 \times 3)}\end{gathered}

\begin{gathered}\longrightarrow\sf{63 = (12x - 9)}\end{gathered}

\begin{gathered}\longrightarrow\sf{63 = 12x - 9}\end{gathered}

\begin{gathered}\longrightarrow\sf{12x = 63 + 9}\end{gathered}

\begin{gathered}\longrightarrow\sf{12x = 72}\end{gathered}

\begin{gathered}\longrightarrow\sf{x =  \frac{72}{12}}\end{gathered}

\begin{gathered}\longrightarrow\sf{x =  6}\end{gathered}

\begin{gathered} \star{\underline{\boxed{\sf{\red{x =  6}}}}}\end{gathered}

Hence, the value of x is 6.
