**Answer:**

The answer is = -4

**Step-by-step explanation:**

3x - 8 = -2

3x = -2 + 8

3x = 6

x = 6 ÷3

x = 2

for x - 6

2 - 6 = -4

Xian and his cousin Kal both collect stamps. Xian has 52 stamps, and Kal has 68 stamps. The boys recently

joined different stamp-collecting dubs. Xian's club will send him 20 new stamps per month. Kai's club will

send him 16 new stamps per month. After how many months will Xlan and Kal have the same number of

stamps? How many stamps will each have?

**Answer:**

In 4 months, they will both have 132 stamps.

**Step-by-step explanation:**

Let x = # of months

52 + 20x = 68 + 16x

4x = 16

x = 4

Plug x value into both expressions and see if it checks out

52 + 20(4) = 68 + 16(4)

52 + 80 = 68 + 64

132 = 132

At a competition with 7 runners, medals are awarded for first, second, and

third places. Each of the 3 medals is different. How many ways are there to

award the medals?

Decide if this is a permutation or a combination, and find the number of ways

to award the medals.

**Answer:**

35 different combinations

**Step-by-step explanation:**

This would be a combination because the same person cannot get all three medals so permutation is not the correct way to calculate this. We use the formula C(n,r)=(nr)=n!(r!(n−r)!)=? where n is the number of total objects and r is the number of objects taken from the total.

A goat is grazing outside of a rectangular barn that has dimensions 20 ft by 30 ft.

He's tied to a corner of the barn with a 12 ft rope. Find the grazing area of the goat.

**Answer:**

**Step-by-step explanation:**

*Refer to attached picture.*

The grazing area of the goat is 3/4 of area of circle with 12 ft radius:

Which of the following describes h(x)=x^5-2x^3+x?

Answer choice is

A. h is an odd function

B. h is neither odd nor even

C. h is an even function

**Answer:**

h is an odd funtion

**Step-by-step explanation:**

this is because h(-x)=h(x)

**Answer: A**

**Step-by-step explanation:**

A sum of odd functions is a odd function

Proof:

[tex]h(x)=x^5-2x^3+x\\\\h(-x)= (-x)^5-2(-x)^3+(-x) \\\\=- x^5-2(-x^3)-(-x)\\\\=-(x^5-2x^3+x)\\\\=-h(x)\\\\So\ h(-x)=-h(x):\ the \ function\ h(x) \ is\ odd.\\[/tex]

Find the area of the following quadrilateral.

Answer: 480

Step-by-step explanation:

The quadrilateral ABCD is a trapezium

The formula for area of trapezium is

Area of trapezium = 1/2 × (parallel side 1 + parallel side 2) × h

So we can place the given values into the formula.

We get

Area = 1/2 × (9+15) × 40

Area = 1/2 × 24 × 40

By multiplying all of them we get

Area = 480cm

the sum of two numbers is 17 and their differance is 3

**Answer:**

10 and 7 are the numbers

**Step-by-step explanation:**

Let the number be x and y, ATQ, x+y=17 and x-y=3, solving it we will get x=10 and y=7

The **sum of two numbers** is** 17** and their** difference is 3**.

Let's define the two numbers as x and y.

**Sum of two numbers is 17**

x + y = 17

**Their difference is 3**

x - y = 3

-----------------------------------------

Solve for x

x + y = 17

**x = 17 - y**

now that we have x, substitued x into x - y = 3

x - y = 3

17 - y - y = 3

17 - 2y = 3

-2y = -14

y = 7

we have y, 7, now let's substitue that into one of the equations to find x

x - y = 3

x - 7 = 3

x -7 + 7 = 3 +7

x = 10

the numbers are 10 and 7

The perimeter of a triangle is 16x−6. If two sides measure 3x+2 and 4x−9, then how long is the third side?

Perimeter of a triangle is the sum of measures of its all three sides, let the other be y,

we know,

[tex] \hookrightarrow \: y + 3x + 2 + 4x - 9 = 16x - 6[/tex]

[tex] \hookrightarrow \: y + 7x - 7 = 16x - 6[/tex]

[tex] \hookrightarrow \: y = 16x - 6 - 7x + 7[/tex]

[tex] \hookrightarrow \: y = 6x + 1[/tex]

hence, measure of the third side is 6x + 1
