since the fourth digit is 3, which is lower than 5, we don't have to change the third digit : it remains a "1"

Kamila [148]

Answer:

1 A the first store.

2. B The second store.

Step-by-step explanation:

1. The store with the dearest towel  is The First one ( $20 compared with $18).

2. The equation for the cost in the first store is P = 20n + 25.

The cost in the second  store is given by P = 18n + 35.

For 15 towels first store charges:

20 * 15 + 25 = $325.

Second store charges:

18 * 15 + 35 =  $305.

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.
