Question

what is the value of x? 3 4 6 8

Explanation:

Step1: Use the property of rectangle

In a rectangle, opposite sides are equal. So, \(10 + 2x=18\).

Step2: Solve the equation for \(x\)

Subtract \(10\) from both sides: \(2x=18 - 10\), which simplifies to \(2x = 8\). Then divide both sides by \(2\): \(x=\frac{8}{2}\).

Answer:

\(4\)
