The answer would be 9. Because, you put 9 in each row adding up to 18 but it would still be a rectangle.

Hope this helps! :)

Consider two circular swimming pools. Pool A has a radius of 48 feet, and Pool B has a diameter of 29.46 meters. Complete the de

Ber [7]

Answer: pool B has a greater circumference.

Step-by-step explanation:

The formula for determining the circumference if a circle is expressed as

Circumference = 2πr

Where

r represents the radius of the circle.

π is a constant whose value is 3.14

Pool A has a radius of 48 feet.

1 foot ≈ 0.305 meters

48 feet = 48 × 0.305 = 14.64 meters

The circumference of pool A is

2 × 3.14 × 14.64 = 91.94 meters

Pool B has a diameter of 29.46 meters. Radius = diameter/2

Radius of pool B = 29.46/2 = 14.73 meters

The circumference of pool B is

2 × 3.14 × 14.73 = 92.5 meters

Therefore, pool B has a greater circumference.

Solve for x 4x^2+28x+49=0

barxatty [35]

4 x^2 + 28 x + 49 = 0
Divide both sides by 4:
x^2 + 7 x + 49/4 = 0
Write the left hand side as a square:
(x + 7/2)^2 = 0
Take the square root of both sides:
x + 7/2 = 0
Subtract 7/2 from both sides:
Answer: x = -7/2

Graph the system of equations on your graph paper to answer the question

UNO [17]

Since we have to solve this system graphically, we'll have to draw both lines.

To draw a line, simply build a little tables with two x,y values: for the first line we have

$\begin{array}{c|c}x&-x+3\\0&3\\1&2\end{array}$

So, you can draw the points (0,3) and (1,2), connect them, and you'll have the graph of the line $y=-x+3$

For the second line we have

$\begin{array}{c|c}x&x+5\\0&5\\1&6\end{array}$

So, you can draw the points (0,5) and (1,6), connect them, and you'll have the graph of the line $y=x+5$

Finally, we have to check where the two lines cross. If your drawing is accurate enough, you'll see that the point you're looking for is (-1, 4)
