Step-by-step explanation:

pool tables are rectanglar

Perimeter = 2L + 2W      =  2(L+W)   ---->>>    Perimeter/2  = L + W  =

         Perimeter/2 - W  =  L

        Area = L×W     

Two equations and two unknowns and  L is substituted into the area equation  

 ---->>  Area = (Perimeter/2 - W) x W

          Area = (Perimeter x W)/2  - W²              solve for W

Area = 36 and  Perimeter = 26

       36 ft² = (26)( W)/2 ft  - W² ft²

       36 ft² = 13W ft - W² ft²

        W² - 13W + 36 = 0            quadratic equation factor solve for W

         (W - 4)(W - 9)  = 0            

There are two roots

        W - 4 = 0   and W - 9 = 0

        W = 4  and  9         W = 9  it doesn't make sense  needs to be < L

Perimeter/2 - W = L

         L = 26/2 - W

            = 13 - 4

         L = 9 ft  and   W = 4 ft

Answer:432

Step-by-step explanation: So any number above 70, you add together. Then you will double it to get the answer. So 71 + 72 + 73 = 216. 216 times 2 = 432

Answer:

(1,6), (2,6), (3,3)

Step-by-step explanation:

Since you  travel 6 miles per hour when paddling and 2 miles per hour when drifting, and the total distance covered is 24 miles, we find the times t and t' of paddling and drifting respectively in which the product 6t + 2t' = 24.

So, for the first values of t and t' , we have t = 1 and t' = 9

So, 6t + 2t' = 6 × 1 + 2 × 9 = 6 + 18 = 24

As an ordered pair (1, 9)

For the second set of values of t and t' , we have t = 2 and t' = 6

So, 6t + 2t' = 6 × 2 + 2 × 6 = 12 + 12 = 24

As an ordered pair (2, 6)

For the third set of values of t and t' , we have t = 3 and t' = 3

So, 6t + 2t' = 6 × 3 + 2 × 3 = 18 + 6 = 24

As an ordered pair (3, 3)

So, the three different combinations of paddling and drifting times are (1,6), (2,6), and (3,3)

Answer:

a = 7

Step-by-step explanation:

3(1 - 2a) = -3a - 18

3 - 6a = - 3a - 18

Add 18 to each side:

3 + 18 - 6a = - 3a - 18 + 18

21 - 6a = - 3a

Add 6a to each side:

21 - 6a + 6a = - 3a + 6a

21 = 3a

3a = 21

Divide each side by 3:

3a ÷ 3 = 21 ÷ 3

a = 7

Answer:

do distributive property on both, so multiply 6•x and 6•-4. then multiply 7•x and 7•3.

so it'll basically be 6x - 24 = 7x + 21.

then add 24 to both sides so: 6x - 24 + 24 = 7x + 21 + 24. since -24+24=0 it'll be 6x = 7x + 21 + 24.

then add 21 + 24 and that will be 45.

so 6x = 7x + 45

then subtract 7x from both sides 6x - 7x = 7x + 45 - 7x

that'll be -x = 7x + 45 - 7x

combine like terms (7x - 7x) = 0

so -x = 45

and since x can't be negative, do the opposite signs

so instead of -x = 45, make it x = -45

Hope it helped! (sorry that's its very long just wanted to show u the steps just in case)

Answer:

What function type does the graphed data points represent?

D, quadratic

The function will be "quadratic" which represents graphed data points. which is the correct answer would be an option (D).

The quadratic function is defined as a function containing the highest power of a variable is two.

The series of x-values into the function and solving for y. You can use any values you like, but it is often helpful to start with a small range of x-values around the vertex and then expand the range as needed.

Plot the points from the table on a coordinate grid, using the x-values as the horizontal axis and the y-values as the vertical axis.

Connect the points with a smooth curve to complete the graph of the quadratic function.

Therefore, the function, which represents graphed data points, will be quadratic.

Hence, the correct answer would be an option (D).

Answer:

  (x -2)^2 + (y +4)^2 = 18

Step-by-step explanation:

To find the constant the expression is equal to, fill in the coordinates of the given point and do the arithmetic.

  (-1 -2)^2 +(-1+4)^2 = 9 + 9 = 18

The equation of the circle is ...

  (x -2)^2 + (y +4)^2 = 18
