Step-by-step explanation:

. You have that:

- The homeowner want the length of the swimming pool to be 4 feet longer than its width.

- He wants to surround it with a concrete walkway 3 feet wide.

- He can only afford 300 square feet of concrete for the walkway.

2. Therefore, the tota area is:

At=L2xW2

L2 is the lenght of the walkway (L2=L1+3+3⇒L2=(W1+4+6)⇒L2=W1+10).

W2 is the width of the walkway (W1+3+3⇒W2=W1+6)

3. The area of the walkway is:

A2=At-A1

A2=300 ft²

4. Therefore, you have that the width of the swimming pool is:

A2=(W1+10)(W1+6)-(W1+4)(W1)

300=(W1²+6W1+10W1+60)-(W1²+4W1)

W1²+16W1+60-W1²-4W1-300=0

12W1-240=0

W1=240/12

W1=20 ft

5. And the length is:

L1=W1+4

L1=20+4

L1=24 ft

Answer:

-6

Step-by-step explanation:

We are given that -x-10y=2 is a true equation so by multiplication property of equality, we can multiply everything by -3 on both sides. This gives us 3x+10y=-6

Step-by-step explanation:

Expression given,

[tex] \\ \longrightarrow \qquad \sf 5x+3x+2y+4y \\ \\ [/tex]

Here, in the expression we have to find the like terms.

So from the expression we that, 5x and 3x are like terms and 2y and 4y are like terms too, so now we have to combine them and then we will get a new expression so.

[tex]\\ \longrightarrow \qquad \sf 8x + 6y \\ \\ [/tex]

So, 8x + 6y is the new expression.

Answer: Danny's supermarket

Step-by-step explanation:

Danny's price- 0.75x1.5= $1.12 for 1 liter water bottle

Marta's price- $1.50 for 1.25 liter water bottle

1.12x1.25=1.40, if Danny was selling a 25% bigger bottle(making the bottle size equal to Marta's) it would cost $1.40, the lower price

Answer: 3.8 in decimal form.

Answer:

126.96

Step-by-step explanation:

Answer: 45.25

Step-by-step explanation: Add all the digits together and divide by 8

Mean is the average

Answer:

45.25

Step-by-step explanation:

The mean is the average. Add up all of the values (45+40+47+50+45+49+40+46). This is equal to 362. The amount of values in the set is 8. Divide 362 by 8 to get the mean of 45.25.

Answer:

A

Step-by-step explanation:

A because the mean absolute deviation of an eighth grade class  is less than that of a seventh grade class. Also, the class size is larger on average for eighth graders (35>31).

Let's plug in a = 9 and b = 14

[tex]a^3 + b^3 = (a+b)(a^2 - ab + b^2)\\\\9^3 + 14^3 = (9+14)(9^2 - 9*14 + 14^2)\\\\9^3 + 14^3 = (9+14)(81 -126 + 196)\\\\9^3 + 14^3 = (23)(151)\\\\9^3 + 14^3 = 3473\\\\[/tex]

It is possible to calculate the terms on the right hand side without a calculator. You can either memorize things, do mental math, or use pencil/paper to do the scratch work.

As a way to verify things,

[tex]9^3 = 9*9*9 = 729\\\\14^3 = 14*14*14 = 2744\\\\9^3+14^3 = 729+2744 = 3473\\\\\text{Therefore, } 9^3 + 14^3 = 3473 \text{ has been proven correct}\\\\[/tex]
