Help! Multiply the following polynomials.

(3x-5)(x-5)

Answer:

17.66m

Step-by-step explanation:

Let the area of the rectangular garden be L²

A = L²

19.5 = L²

L = √19.5

L = 4.416

Perimeter = 4L

Perimeter = 4(4.416)

Perimeter of the garden =17.66m

Hence the number of meters of fencing that are needed to go around the​ garden is 17.66m

Answer:

1 in 3 chance.

Step-by-step explanation:

the numbers 3, 6, 9, and 12 can all be divided by 3 and that's 4 out of the 12 numbers, and that's 1/3 simplified.

Answer:

a. h = A/w = 2 ³/₄ ft

b. A'/A = 2/3

Step-by-step explanation:

a. What is the total height of the wall? Write an equation to represent the situation. Then solve.

The wall is a rectangle and its area is A = wh where w = width and h = height of wall.

Making h subject of the formula,

h = A/w

Now, Since the area of the retaining wall, A is 23 ³/₈ ft² and its width is the length of the portion of the wall which is brick w is 8 ¹/₂ ft, then

h = A/w

= 23 ³/₈ ft² ÷ 8 ¹/₂ ft

= 187/8 ft² ÷ 17/2 ft

= 187/8 ft² × 2/17 ft

= 187/4 ft² × 1/17 ft

= 187/68 ft

= 2 ³/₄ ft

b. If the area of the brick portion of the wall is 15(7/12), what fraction of the wall is brick? Write an equation to show your work.

Since the area of the brick portion of the wall is A' = 15 ⁷/₁₂ ft²  and the total are of the retaining wall is A =  23 ³/₈ ft²

The fraction of the wall that is brick = A'/A

= 15 ⁷/₁₂ ft² ÷ 23 ³/₈ ft²

= 187/12 ÷ 187/8

= 187/12 × 8/187

= 8/12

= 2/3

Answer with Step-by-step explanation:

a) 2 3/4 ÷ 3 = 11/12 feet

11/12 + 11/12 = 1 5/6

Or, you could write an algebraic equation:

2 3/4 ÷ 3 = x.  (3x = 2 3/4)

x = 11/12

The height of the brick proportion of the wall is 1 5/6

b)

You know that 8 x 2 is 16. Well, you already know that the whole total of fractions, multiplied together, would probably be less that 1 and less than 1/2.

So, your rounded answer should be 16. Or 16 1/2

c)  

Area = 8 1/2 x 2 3/4.

Use Distributive Property to solve the area.

(8 x 2) + (3/4 x 1/2) = x

8 x 2 = 16

3/4 x 1/2 = 3/8

16 + 3/8 = 16 3/8

x = 16 3/8

I think my answer is reasonable because I estimated 16, and 1/2. 3/8 is close to 1/2. That's why my answer is reasonable.

I got you bro!

Answer:

{x,y} = {4-1}

You might be wondering how I got this, well here are the steps:

System of Linear Equations entered :

  [1]    2x + y = 7

  [2]    x - 2y = 6

Graphic Representation of the Equations :

   y + 2x = 7        -2y + x = 6  

Solve by Substitution :

// Solve equation [2] for the variable  x  

 [2]    x = 2y + 6

// Plug this in for variable  x  in equation [1]

  [1]    2•(2y+6) + y = 7

  [1]    5y = -5

// Solve equation [1] for the variable  y  

  [1]    5y = - 5

  [1]    y = - 1

// By now we know this much :

   x = 2y+6

   y = -1

// Use the  y  value to solve for  x  

   x = 2(-1)+6 = 4

Solution :

{x,y} = {4,-1}

I hope this has helped you and have a wonderful day!

Answer:

1.9

Step-by-step explanation:

Gabrielle uses 7.6 pints of blue and white paint to paint her bedroom

1/4 of the paint is blue paint

Therefore the amount of white paint she used to paint her bedroom can he calculated as follows

= 1/4

= 0.25×100

= 25%

25/100×7.6

= 2.5 × 7.6

= 1.9

Hence 1.9 pints of white paint was used to paint the room

Answer:

200 in^2

Step-by-step explanation:

First step- the first square shows the lenght and the bottom shows the width and 10 times 10 is 100

step 2- so the first is 100 double it and 100 times 2 is 200

Step 3- so 200 inches^2 is your anwser.

Answer:

6 teachers and 10 tutors.

Step-by-step explanation:

if there are 120 student and they need 3 teachers per 63 students then there would be 6 teachers because 63x2=126 subtract the six and you get the number of students. 120 so 6 teachers and if they need 5 tutors per 60 student then double the students to get 120 and double the tutors to get 10.

Answer:

54/120

Step-by-step explanation:

Ratio to 54 seconds to 2 minutes is 9 : 20

Find:

Ratio to 54 seconds to 2 minutes

Computation:

We know that,

1 minutes = 60 second

So,

2 minutes = 120 second

Ratio to 54 seconds to 2 minutes = 54 / 120

Ratio to 54 seconds to 2 minutes = 27 / 60

Ratio to 54 seconds to 2 minutes = 9 : 20
