Answer:

x=7

Step-by-step explanation:

-65 = X - 6(2x - 2)

-65 = x - 6*2x - 6*(-2)

-65 = x - 12x + 12

-65 - 12 = - 11x

-77 = -11x

x = -77:(-11)=7

The volume of the figure is 54 cubic units

<h3>Area of a rectangular prism.</h3>

Since we are not given a figure, we can assume it as a rectangular prism:

Area of the rectangular prism = a²b

a² is the base area
b is the height of the prism

Given that a = 3 units and b = 6 units, the required volume is expressed as:

V = 3² * 6

V = 9 * 6

V = 54 cubic units

Hence the volume of the figure is 54 cubic units

A rectangular bathroom floor is covered with square tiles that are 1 1/2 feet by 1 1/2 feet. The length of the bathroom floor is

kenny6666 [7]

Answer:

The number of square tiles required to cover the bathroom floor is approximately 31.

Step-by-step explanation:

The dimensions of the rectangular floor of the bathroom are:

Length = 10.5 ft.

Breadth = 6.5 ft.

The dimensions of the square tiles are:

Side = 1.5 ft.

The area of the rectangular floor of the bathroom is:

$Area\ of Bathroom\ floor=Length\times Breadth\\=10.5\times6.5\\=68.25$

The area of 1 square tile:

$Area\ of\ 1\ square\ tile=(SIde)^{2}\\=(1.5)^{2}\\=2.25$

The number of tiles required to cover the bathroom floor is:

$Number\ of\ tiles=\frac{Area\ of\ bathroom\ floor}{Area\ of\ 1\ square\ tile} \\=\frac{68.25}{2.25}\\ =30.3333\\\approx31$

Thus, the number of square tiles required to cover the bathroom floor is approximately 31.
