Answer:

Area of square = Side²

Step-by-step explanation:

The area of a 2-D region, form, or flattened lamina in the planes is the quantity that represents its extent. On the 2-D surface or 3-D object, surface is its counterpart. A shape's area can be calculated by comparing it to squares of a specific size.

The shed is filled with sawdust whose density (kg/m3) at any point is proportional to the distance of that point from the floor.
postnew [5]
It is important to note that when we say proportional, the increase in the value of the independent variable (in this case, distance x) will also increase the value of the dependent variable (density, d). Using k as the proportionality constant, the answer to this question would then be,
                                        d = kx

The above expression is not in its simplest form, and we need to simplify it, that is what asked in the question.

Given equation,

(9 {x}^{2}  - 3x + 7) + ( - 3 {x}^{2}  + 2)

First of all, let's open the parentheses to combine the like terms for simplifying.

9 {x}^{2}  - 3x + 7 - 3 {x}^{2}  + 2

Arranging the like terms, x² with x², x with x and constant terms near to each other.

9 {x}^{2}  - 3 {x}^{2}  - 3x + 7 + 2

Simplying further,

(9 - 3) {x}^{2}  - 3x + 9

6 {x}^{2}  - 3x + 9

So, the correct option is C
