Question

Question:

1. In the square at the right, state the value of $\text{x}$.

A. 1 B. 2

C. 3 D. 4

Short answer

Thevalue of $\text{x}$ is $\mathbf{2}$ and the correct option isB.

Step-by-step solution

- State the definition of a variable.

A variable is a term that is used to represent an unknown value.

- Evaluate the value of x.

It is know that, in a square all the 4 sides are equal.

Consider the diagram,

As, the diagram is a square, then all sides are equal, then,

$5x=x+8$.

Simplify the equation using subtraction,

$\begin{array}{c}5x-x=x+8-x\\ 4x=8\\ x=2\end{array}$

Hence, the value of x is 2.

- State the conclusion.

Therefore, the correct option is B that is 2.
