Answer:

The equation would be:

3x + 2 = 7*2

Step 1. Subtract 2 from both sides:

3x = 6*2

Step 2. Divide both sides by 3:

3x/3 = 6*2/3
x = 2*2

A single box weights x= 4 units.

a) Solution:

The equation that is represented by the diagram below will be,

→ 3x + 2 = 7 × 2

b) Solution:

The steps that can be taken are,

→ 3x + 2 = 7 × 2

→ 3x = 14 - 2

→ 3x = 12

→ x = 12/3

→ [x = 4]

c) Solution:

A single box weighs 4 units (kg), because the required value of x is 4.

Find the area of the carpet tile. Then find the area covered by 120 carpet tiles.

weqwewe [10]

The area of the carpet is the amount of space it occupies

The area of the carpet tile is 256 square inches
The area covered by 120 tiles is 30720 squares inches

<h3>How to determine the carpet area</h3>

The dimension of the carpet tile is 16 inches by 16 inches

So, the area is:

$Area = 16 * 16$

Evaluate the product

$Area = 256$

Hence, the area of the carpet tile is 256 square inches

For 120 carpet tiles, the area is:

$Area = 120 * 256$

$Area = 30720$

Hence, the area covered by 120 tiles is 30720 squares inches

Answer:

A. $\frac{(a-b)^{2} +b^{2} }{a^{2}}$

Step-by-step explanation:

So to get the area of a square, we need to find the length of one side.

We know the length of the larger square is a, so the area of the larger cube is $a^{2}$

We can find the length of a side of the smaller square by using pythagoreans theorem to find the hypotenuse of the triangle formed in the bottom left corner. The length of one side along the x axis is a - b, and the length of the other side, along the y-axis, is b.

We can plug it into pythagoreans theorem to get

$(a-b)^{2} +b^{2} = C^{2}$ (C represents the length of one side of the smaller square, and the hypotenuse of the triangle)

$C = \sqrt{ (a-b)^{2} +b^{2}}$

The area of the smaller triangle is C squared to the area of the smaller triangle is

$(a-b)^{2} +b^{2}$

To get the ratio of the smaller square in comparison to the larger square we divide the area of the smaller square by the area of the larger square.

So the ratio should be

$\frac{(a-b)^{2} +b^{2} }{a^{2}}$
