Step-by-step explanation:

Distribute parentheses:

[tex]=xx^2+x\left(-7x\right)+x\cdot \:12+6x^2+6\left(-7x\right)+6\cdot \:12[/tex]

Apply minus - plus rule:

Its complicated but..

Step-by-step explanation:

( x + 6 ) ( x^2 - 7x + 12 )

x ( x^2 - 7x + 12) + 6 ( x^2 - 7x + 12 )

x^3 - 7x^2 + 12x + 6x^2 - 42x + 72

x^3 + 6x^2 + 12x - 42x - 7x^2 + 72

19x - 49x + 72

30x + 72

x = 72/30

Answer:

The sets of ordered pair which are functions are;

III. {(3, 0.3), (-3, 0.3)} and IV. {(-2, 2), (2, -2)}

Step-by-step explanation:

The given ordered pairs are;

I. {(2, 3), (2, 4)}, III. {(3, 0.3), (-3, 0.3)} IV. {(-2, 2), (2, -2)}

A combination of ordered pair represent a function if each input is associated with only one output

Therefore, we have;

For I, the single input value, 2 maps to two output values, 3 and 4, therefore, the set of ordered pair {(2, 3), (2, 4)} does not describe a function

For II, the input values, 3 and -3 maps to the single output value, 0.3, therefore, each input has only one output and the set of ordered pair {(3, 0.3), (-3, 0.3)} describes a function

For IV, the input values, -2 and 2 maps to the output values, 2, and -2 therefore, each input has only one output and the set of ordered pair {(-2, 2), (2, -2)} describes a function

The pattern as the exponent decreases is (c) divide the previous value by 5

The sequence on the table are given as:

125, 25, 5, 1, 1/5, 1/25......

From the above sequence, we have:

125/5 = 25

This means that the current value is gotten by dividing the previous by 5

Hence, the pattern as the exponent decreases is (c) divide the previous value by 5

Answer:

1060 feet

Step-by-step explanation:

The computation of the perimeter of the rectangle is as follows;

As we know that

Perimeter of the rectangle = 2 × ( length + width)

where

Length of x = 5

And, the width be 5x^3 - 4x^2

= 5(5)^3 - 4(5)^2  

= 625 - 100  

= 525

Now the perimter is

= 2 × (5 + 525)

= 1060 feet

Answer:

Step-by-step explanation:

if you have one side =2/7

area = (2/7)^2=4/49 m^2

To find the area of a square, we need to know the length of one of its sides. In this case, the given length of a side is 2/7m. So, the area of the square is 4m² / 49.

To find the area, we use the formula A = s², where A represents the area and s represents the length of a side. Let's substitute the given value into the formula:

A = (2/7m)²

To square 2/7m, we multiply it by itself:

A = (2/7m) × (2/7m)

To multiply fractions, we multiply the numerators together and the denominators together:

A = (2 × 2) / (7 × 7) × m × m

Simplifying the numerator and denominator:

A = 4 / 49 × m × m

Finally, we can write the area as a fraction:

A = 4m² / 49

So, the area of the square is 4m² / 49.

Answer:

There were 200 children and 400 adults in the auditorium.

Step-by-step explanation:

Given that there were a total of 600 peoples in the event.

Let there were n children in the event.

So, the number of an adult in the event = 600-n

As the admission price for one child = 15 pesos

and the admission price for one adult = 25 pesos.

So, total admission price = 15n+25(600-n)

As total money raised = 13000 pesos

So, 15n+25(600-n)=13000

15n+15000-25n=13000

10n=15000-13000=2000

n=2000/10=200

Therefore, number of children = 200

and the number of adults = 600-200=400.

Hence, there were 200 children and 400 adults in the auditorium.

Answer:

[tex]y = 1.4[/tex]

Step-by-step explanation:

Given

[tex]y = width[/tex]

[tex]x = length[/tex]

[tex]y = 3;\ when\ x = 14[/tex]

Required

Find y when x = 30

Being an inverse variation, we have:

[tex]y\ \alpha\ \frac{1}{x}[/tex]

Convert the variation to an equation

[tex]y = \frac{k}{x}[/tex]

First, we solve for k

Make k the subject to solve for k

[tex]k = xy[/tex]

[tex]y = 3;\ when\ x = 14[/tex]

So, the value of k is:

[tex]k = 14 * 3[/tex]

[tex]k = 42[/tex]

To solve for y when x = 30

Substitute 30 for x and 42 for k in [tex]k = xy[/tex]

[tex]42 = 30 * y[/tex]

Make y the subject

[tex]y = \frac{42}{30}[/tex]

[tex]y = 1.4[/tex]

The width of the rectangle would be as follows:

[tex]1.4[/tex]  inches

Inverse proportion occurs when one value increases and the other decreases.

The width, [tex]y[/tex], of a rectangle with a fixed area varies inversely with its length, [tex]x[/tex].

So, [tex]y=\frac{k}{x}[/tex] where [tex]k[/tex] is the constant.

The width is [tex]3[/tex] inches when the length is [tex]14[/tex] inches.

So,

[tex]3=\frac{k}{14} \\k=42y=\frac{42}{x}\\Put x=30[/tex]

Therefore, [tex]y=\frac{42}{30}=1.4[/tex] inches

Thus, Width is [tex]\boldsymbol{1.4}[/tex] inches when the length is [tex]30[/tex] inches.

Step-by-step explanation: basically its 6 + 1 = 7x

6 - 14 = 8x  9 + 4 = 13x

Answer: x = 9

Explanation: In this problem, we're given a triangle and information

about each of its angles and we're asked to find the value of x.

The measures of the angle of a triangle always add to 180 degrees.

So we can setup the equation 6x + 1 + 9x + 4 + 6x - 14 = 180.

Simplifying on the left side, we have 21x - 9 = 180.

Adding 9 to both sides, we have 21x = 189.

Now divide both sides by 21 to get x = 9.
