3x2+2-5x - 42x - 7-2x2+10Hint: To Find The Perimeter Of A Polygon, Add All The Sides

Answers

Answer 1

Answer:

The perimeter of a 4-sided polygon: P = x²-3x+1

Step-by-step explanation:

Given the lengths of the sides of a given polygon

3x²+2-2x²+102x-7-5x-4

The perimeter of a 4-sided polygon can be determined by adding the lengths of all 4 sides.

Perimeter = (3x²+2) + (-2x²+10) + (2x-7) + (-5x-4)

Remove the parentheses

                =3x²+2-2x²+10+2x-7-5x-4

Group like terms

                =3x²-2x²+2x-5x+2+10-7-4

Add similar elements:   3x²-2x²=x²

                 =x²+2x-5x+2+10-7-4

Add similar elements:   2x-5x=-3x

                 =x²-3x+2+10-7-4

                 =x²-3x+1

Therefore, the perimeter of a 4-sided polygon: P = x²-3x+1

A holiday decoration involves blue and white lights.The ratio of blue lights to white lights is 3 to 2 . The box the decoration came in stated that the number of blue lights was 114 but didn't give the number of white lights or the total number of lights.

Answers

Answer:

a. 76 b. 190

Step-by-step explanation:

a. Number of white lights

Since the ratio of blue lights to white lights is 3 to 2 and the number of blue lights is 114, it follows that 3 : 2 = 114 : x where x is the number of white lights.

So, 3/2 = 114/x

cross-multiplying,

3x = 114 × 2

3x = 228

x = 228/3

x = 76

b. Total number of lights

So, the total number of lights is thus number of blue lights + number of white lights = 114 + 76 = 190

How many expressions can you find using and that have a value of 12 a=6 b=4 c=-2

Answers

Answer:

Step-by-step explanation:

Some of the expressions that can be derived that have the values of 12 are:

i. 2a = 2 x 6

      = 12

ii. 3b = 3 x 4

        = 12

iii. (b  + c) x a = (4 - 2) x 6

                = 2 x 6

                = 12

iv. 2b + [tex]c^{2}[/tex] = (2 x 4) + (-2 x -2)

                = 8 + 4

                = 12

v. [tex]b^{2}[/tex] -  [tex]c^{2}[/tex] = (4 x 4) - (-2 x -2)

             = 16 - 4

             = 12

vi. [tex]c^{4}[/tex] - b = (-2 x -2 x -2 x -2) + 4

             = 16 - 4

This CD case is a rectangle that is 5.5” tall by 5.75” wide. What is the area of the CD case?

Answers

31.625

Step-by-step explanation:

Multiply height by width so

5.5(5.75) = 31.625

The area of the CD case will be [tex]31.625[/tex] squared inch .

What is area ?

Area is the quantity that expresses the extent of a region on the plane or on a curved surface.

Area [tex]= Length * Breadth[/tex]

We have,

A rectangle.

Length of rectangle [tex]=5.5"[/tex]

Breadth of rectangle [tex]=5.75"[/tex]

So,

The area of rectangle [tex]= Length * Breadth[/tex]

                                    [tex]=5.5*5.75[/tex]

                                    [tex]= 31.625[/tex] squared inch

So, the area of CD case is [tex]31.625[/tex] squared inch.

Hence, we can say that the area of the CD case will be [tex]31.625[/tex] squared inch .

Thomas has two bags, one bag with 6 yellow and 5 red marbles, and one with 2 green and 4 blue marbles. If his friend Nick pulls one marble from each bag, what is the probability of him getting one red and one blue marble?

Answers

probability of red is 5/11
probability of blue is 2/3
multiply them together to get about a thirty percent chance

The probability of him getting one red marble from 5 red marbles in one bag and one blue marble from 4 blue marbles in the other bag is 4/11.

What is probability?

It is the chance of an event to occur from a total number of outcomes.

The formula for probability is given as:

Probability = Number of required events / Total number of outcomes.

We have,

Number of marbles in first bag = 11

Yellow marbles = 6

Red marbles = 5

Number of marbles in the second bag = 6

Green marbles = 2

Blue marbles = 4

The probability of him getting one red and one blue marble.

= [tex]\frac{^5C_1}{^{11}C_1} \times\frac{^4C_1}{6^C_1}[/tex]

= 5/11 x 4/5

= 4/11

Thus,

The probability of him getting one red and one blue marble is 4/11.
