Answer:

16.1=x

Step-by-step explanation:

2.1(0.2x-1.4)=1.3(0.4x-3.5)  Distribute          

0.42x-2.94=0.52x-4.55  Combine like terms

+4.55                     +4.55  

0.42x+1.61=0.52x

-0.42x         -0.42x  

<u>1.61</u>=<u>0.1x</u>

0.1     0.1              

16.1=x

Find the area A of the polygon with the given vertices.
Natalija [7]

Answer:

A = 35 square units

Step-by-step explanation:

Formula to calculate the distance between two points (x_1,y_1) and (x_2,y_2) is,

d = \sqrt{(x_2-x_1)^2+(y_2-y_1)^2}

Length of the segment between A(2, 2) and B(9, 2) = \sqrt{(9-2)^2+(2-2)^2}

                                                                                     = 7 units

Length of the segment between B(9, 2) and C(9, -3) = \sqrt{(9-9)^2+(2+3)^2}

                                                                                       = 5 units

Length of the segment between C(9, -3) and D(2, -3) = \sqrt{(9-2)^2+(-3+3)^2}

                                                                                        = 7 units

Length of the segment between A(2, 2) and D(2, -3) = \sqrt{(2-2)^2+(2+3)^2}

                                                                                       = 5 units

Therefore, given polygon is a rectangle.

Area of the rectangle = length × width

                                    = 7 × 5

                                    = 35 square units

Express the area of the entire rectangle. Your answer should be a polynomial in standard form.
disa [49]

The standard size of the rectangle's area is x² + 12x + 35

Given:

a diagram that depicts the polynomial that denotes a rectangle's length and width.

The rectangle's area is equal to its length x width.

Given that length is equal to x + 7 and width is equal to x + 5, the area is equal to length plus width.

Add the numbers in brackets: Area = x2 + 5x + 7x + 35

Area = x2 + 12x + 35

A quadrilateral with equal angles and parallel opposite sides is referred to as a rectangle. We are surrounded by numerous rectangular objects. The length and width of a rectangular shape are the two dimensions that define it. The rectangle's length and width are its longer and shorter sides, respectively. We will learn about the properties of the rectangle shape in this chapter.
