How do you find the area of a 2x-3 square

Answer:

a3 = 112

Step-by-step explanation:

a2 + a1 = a4

So

3x + 20 = 4x + 4

x = 16

a4 = 68

180 - 68 = 112

The division equation that satisfies the required parameters where 13 is the quotient is 1/1/13 = 13

The given parameters are:

A division equation is represented as:

Dividend/Divisor = Quotient

Substitute Quotient = 13

Dividend/Divisor = 13

A unit fraction is represented as 1/n, where n is an integer.

So, the divisor can be represented as 1/13

Dividend/1/13 = 13

Divide both sides by 13

Dividend = 1

So, we have:

1/1/13 = 13

Hence, the division equation is 1/1/13 = 13

Answer:

By multiplying the term by itself (x+1)(x+1)

Some people like to use the box technique, which formats like this:

    x      +     1

x   x^2        1x

+  

1    1x           1

The terms multiply in columns, and then add all together

So

x^2 + 1x + 1x + 1 can be simplified to x^2+2x+1 = 0, which is the perfect square of (x+1)^2 = 0

Answer:

[tex]a=12[/tex]

Step-by-step explanation:

Pythagorean Theorem: [tex]a^{2}+b^{2}=c^{2}[/tex]

In this case, a = 9, b = a, and c = 15.

[tex]9^{2}+a^{2}=15^{2}[/tex]

[tex]81+a^{2}=225[/tex]

The, we subtract 81 from both sides getting:

[tex]a^{2}=144[/tex],

Then, [tex]a=12[/tex]

Answer:

x=2, y=-4

Step-by-step explanation:

If you put a vertical or horizontal line straight through the shape and it looks the same, then it is symmetrical. You can put a symmetrical line both vertically AND horizontally. To do this, you just need a line going through the points at the tips and the points at the sides of the quadrilateral. A line that is vertical will be an x=, because it only covers one x-value. So, the line for x will be x=2, because it goes through both tips of the quadrilateral. A horizontal line will be y= because it only covers one y-value. So, the line for the horizontal line will by y=-4, because this goes through both sides of the quadrilateral.

Given the volume of the space in the pot and the volume of the meatballs, the sauce will not spill over.

The first step is to determine the volume of the remaining space that the sauce is yet to fill. A pot usually has the shape of a cylinder, so the formula for the volume of a cylinder would be used.

Volume of a cylinder = πr²h

π x (14/2)³ x 2 = 98 in³

The second step is to determine the volume of the two dozen meatballs.

Volume of a sphere = 4/3πr³

24 x (4/3 x π x (2/2)³) = 32π in³

The sauce will spill over if the volume of the pot is less than 146π in³ and it will not spill over if the volume of the pot is more than 146π in³.

The volume of sauce in the pot is calculated as follows;

V = πr²h

V = π x (7)² x (2)

V = 98π in³

Area of 1 meatball = πr² = π x (1)² = π in²

Area of the 2 dozen = (2 x 12) x A

                                       = 24 x π in² = 24π in²

the height of each meatball = 2 in,

Volume of the 2 dozens = 2 in x 24π in² = 48π in³

Total volume of the meatball and sauce in the pot = 98π + 48π = 146π in³

Thus, the sauce will spill over if the volume of the pot is less than 146π in³ and it will not spill over if the volume of the pot is more than 146π in³.

The statement that correctly compares the slopes of the linear functions is: the slope of g(x) is less than the slope of f(x).

Slope of a linear function = change in y / change in x = rise/run

Given the linear functions, g(x) and f(x) as shown in the image attached:

Slope of g(x) = 1/2 = 0.5

Slope of f(x) = 2/1 = 2

Therefore, we can conclude that: the slope of g(x) is less than the slope of f(x).
