Find the perimeter and area of the figure below

Answer:

m<ABC = 92

Step-by-step explanation:

(3x + 23) and 4x are equal angle wise. So we have the equation:

(3x + 23) = 4x

3x = 4x - 23

-x = -23

x = 23

Multiply x by 4 which is 92

Answer:

[tex]\frac{9}{14}[/tex]

Step-by-step explanation:

1. Add two fractions together.

[tex]\frac{3}{7}[/tex] + [tex]\frac{6}{7}[/tex] = [tex]\frac{9}{7}[/tex]

2. Divide by 2.

[tex]\frac{9}{7}[/tex] ÷ 2 = [tex]\frac{9}{14}[/tex]

Answer:

Jerry, Antonio, Jenny

Step-by-step explanation:

To solve this, we can represent the numbers as fractions, make them have one common denominator, and go from there

First, we can represent these as fractions:

Jenny:

four-fifths = 4/5

Antonio:

seven-eighths = 7/8

Jerry:

three-fourths = 3/4

Next, we can find the lowest common multiple. We can do this by listing the multiples of each number until something is in common for all 3

4:

4, 8, 12, 16, 20, 24, 28 ,32, 36, 40, 44, 48

8:

8, 16, 24, 32, 40, 48, 56, 64

5:

5, 10, 15, 20, 25, 30, 35, 40, 45, 50, 55, 60

One number that is in common is 40.

Our next step is to find out what we need to multiply each number by to equal 40. We can do this via division.

4:

40/4 = 10

8:

40/8 = 5

5:

40/5 = 8

Next, we can multiply the numerator and denominator by the same number, essentially multiplying it by 1. For example, 4/5 * 5/5 = 20/25, which is still equal to 4/5 because 5/5 = 1 and multiplying any number by 1 keeps it the same.

3/4 * 10/10 = 30/40

7/8 * 5/5 = 35/40

4/5 * 8/8 = 32/40

We can see that 3/4 (Jerry) is the lowest, 7/8 (Antonio) is the highest, and 4/5 (Jenny) is in the middle

[tex]990:(12-9)^2=990:3^2=\\\\=990:(3\cdot3)=990:9=\boxed{110}[/tex]

Answer:

(a).

[tex]S_{n} = \frac{n}{2} (4n + 20) \\ \\S _{n - 1} = \frac{(n - 1)}{2} (4n - 4 + 20) \\ \\ S _{n - 1} = \frac{(n - 1)}{2} (4n + 16) \\ \\S _{n - 1} = \frac{(n - 1)(4n + 16)}{2} \\ \\ { \boxed{S _{n - 1} = {2 {n}^{2} + 6n - 8}}} \\ [/tex]

(b).

from general equation:

[tex]S _{n - 1} = \frac{(n - 1)}{2} (4n + 16)[/tex]

first term is 4n

common difference:

[tex]16 = \{(n - 1) - 1 \}d \\ 16 = (n - 2)d \\ d = \frac{16}{n - 2} [/tex]

Answer:

  Each colored block in Figure 20 will be a 20×20 square of smaller squares of the same color. The red-green pattern will be identical.

Step-by-step explanation:

Each colored block in Figure N is an N×N array of small blocks the same color. The pattern of red and green N×N blocks is the same from one figure to the next. We expect Figure 20 to fit this description.

Answer:

There are 12 horses and 18 geese.

Step-by-step explanation:

We are given that in a field full of horses and geese, a farmer notes that there are 30 heads and 84 feet.

We can write a system of equations using the given information.

Let the amount of horses there are be represented by h and geese by g.

Assuming each horse and geese has only one head, we can write that:

[tex]\displaystyle h + g= 30[/tex]

And assuming that each horse has four feet and each geese has two feet, we can write that:

[tex]4h + 2g = 84[/tex]

This yields a system of equations:

[tex]\displaystyle \left\{\begin{array}{l} h + g = 30 \\ 4h + 2g = 84 \end{array}[/tex]

We can solve it using substitution. From the first equation, isolate either variable:

[tex]g = 30 - h[/tex]

From the second, we can first divide by two:

[tex]2h + g = 42[/tex]

And substitute:

[tex]2h + (30 - h) = 42[/tex]

Combine like terms:

[tex]h + 30 = 42[/tex]

Subtract:

[tex]h = 12[/tex]

Therefore, there are 12 horses.

And since the total number of animals is 30, there must be 30 - 12 or 18 geese.

In conclusion, there are 12 horses and 18 geese.

The rational expressions that sum to  [tex]\frac{2x+3}{(x+3)(x-5)} = \frac{2x}{(x+3)(x-5)} + \frac{3}{(x+3)(x-5)}[/tex]

The given expression is:

[tex]\frac{2x+3}{x^2-2x-15}[/tex]

Factorize the denominator

[tex]x^2-2x-15\\x^2-5x+3x-15\\x(x-5)+3(x-5)\\(x+3)(x-5)[/tex]

The given expression therefore becomes:

[tex]\frac{2x+3}{(x+3)(x-5)}[/tex]

This can be split into the sum:
