Question

what is the value of x? 10 + 2x 2y + 4 18 10

Explanation:

Step1: Use the property of a rectangle (opposite sides are equal)

For the length of the rectangle: \(10 + 2x=18\)

Step2: Solve the equation for \(x\)

Subtract \(10\) from both sides: \(2x=18 - 10\), so \(2x = 8\).
Divide both sides by \(2\): \(x=\frac{8}{2}\)

Answer:

\(4\)
