Tom compared \dfrac{2}{12} 12 2 ​ start fraction, 2, divided by, 12, end fraction and \dfrac{7}{6} 6 7 ​ start fraction, 7, divi

ded by, 6, end fraction by first comparing each fraction to \dfrac{1}{2} 2 1 ​ start fraction, 1, divided by, 2, end fraction and 111. Step 1: \dfrac{2}{12} 12 2 ​ start fraction, 2, divided by, 12, end fraction is less than \dfrac{1}{2} 2 1 ​ start fraction, 1, divided by, 2, end fraction. Step 2: \dfrac{7}{6} 6 7 ​ start fraction, 7, divided by, 6, end fraction is less than 111 but more than \dfrac{1}{2} 2 1 ​ start fraction, 1, divided by, 2, end fraction. Step 3: So, \dfrac{2}{12} < \dfrac{7}{6} 12 2 ​ < 6 7 ​ start fraction, 2, divided by, 12, end fraction, is less than, start fraction, 7, divided by, 6, end fraction In which step did Tom make his first mistake?

Find the possible dimensions of the picture above please
Svetlanka [38]

Answer:

(2x – 7) × (2x + 7)

Step-by-step explanation:

From the question given above, the following data were obtained:

Area (A) = (4x² – 49) m²

Dimension =?

The picture in the question above has a rectangular shape. Thus, the area is given by:

Area (A) = Length (L) × Width (W)

A = L × W

The dimension of the shape will be:

L × W

Now, we shall determine the dimension (L × W) as follow:

Area (A) = (4x² – 49) m²

Dimension (L × W) =?

A = L × W

L × W = 4x² – 49

Recall:

4 = 2²

49 = 7²

Thus,

L × W = 2²x² – 7²

L × W = (2x)² – 7²

Different of two squares

L × W = (2x – 7)(2x + 7)

L × W = (2x – 7) × (2x + 7)

Dimension = (2x – 7) × (2x + 7)

Therefore, the possible dimension (L × W) of the shape is (2x – 7) × (2x + 7)

Complete the coordinate proof of the theorem.
mojhsa [17]
C(a,b), because the x-coordinate( first coordinate) is a (seeing as it is situated directly above point B, which also has an x-coordinate of a) and the y-coordinate ( second coordinate) is b (seeing as it is situated on the same horizontal level as point D, which also has a y-coordinate of b)

the length of AC can be calculated with the theorem of Pythagoras:

length AB = a - 0 = a
length BC = b - 0 = b

seeing as the length of AC is the longest, it can be calculated by the following formula:

It is called "Pythagoras' Theorem" and can be written in one short equation:

a^2 + b^2 = c^2 (^ means to the power of by the way)

in this case, A and B are lengths AB and BC, so lenght AC can be calculated as the following:

a^2 + b^2 = (length AC)^2
length AC = √(a^2 + b^2)

Extra information: Seeing as the shape of the drawn lines is a rectangle, lines AC and BD have to be the same length, so BD is also √(a^2 + b^2). But that is also stated in the assignment!
