[45/(2 * 4.7) - (4.4)] * 6 = 54

Step 1: PEMDAS (Parenthesis first) 
2 × 4.7 = 9.4

Step 2: Still within the parenthesis: 9.4 - 4.4 = 5

Step 3: Finish within the parenthesis: 45 ÷ 5 = 9

Step 4: Last part of the equation: 9 × 6 = 54

Correct placement of brackets and parenthesis to make the statement true is:

[45/(2x4.7)-(4.4)]x6 = 54

The area of a 2D form is the amount of space within its perimeter. The area of the rectangle is 12 units². Thus, the correct option is A.

<h3>What is an area?</h3>

The area of a 2D form is the amount of space within its perimeter. It is measured in square units such as cm2, m2, and so on. To find the area of a square formula or another quadrilateral, multiply its length by its width.

As per the given information, the graph of the rectangle can be made as shown below. It can be observed from the graph that the length of the rectangle and width of the rectangle are 4 units and 3 units, respectively. Therefore, the area of the rectangle is,

Area = 4 units × 3 units = 12 units²

Hence, the area of the rectangle is 12 units². Thus, the correct option is A.

What is the value of 2x to the third power+4x to the second power 3x to the second power-6x when x=3?
jek_recluse [69]
Hi! So to solve for these, all you have to do is keep PEDMAS in mind. For example, for 2x^3 (Just a fancy way of writing "to the third power") first plug in 3: 2(3)^3 and take it to the third power because E (exponent) comes before M (multiplication) in PEDMAS. You should get 2(27) which then equals 54. Hope this helps:)
