Angelina_Jolie [31]

The simplification form of the expression is 3x²/2 + 2x or three-halves x squared + 2 x option second is correct.

<h3>What is the area of the rectangle?</h3>

It is defined as the area occupied by the rectangle in two-dimensional planner geometry.

The area of a rectangle can be calculated using the following formula:

Rectangle area = length x width

We have:

A community garden with raised beds is being redesigned. The area of the new rectangular beds can be expressed as one-half x (3 x + 4).

The expression:

\rm = \dfrac{1}{2}(3x+4)

By using the distributive property:

\rm = \dfrac{1}{2}\times3x^2+\dfrac{1}{2}\times4x

\rm = \dfrac{3}{2}x^2+2x

Thus, the simplification form of the expression is 3x²/2 + 2x or three-halves x squared + 2 x option second is correct.
