4r-4
4(3)-4
4 multiplied by 3 subtracted by 4
4(3) = 12-4
12 + (-4)
the subtraction changes to addition making the 4 negative.
12 + (-4) = positive 8.
I'm not positive this is 100% correct though.

A backyard pool has a concrete walkway around it that is 3 feet wide on all sides. The total area of the pool and the walkway is

Sloan [31]

Answer:

$x \approx 21.080\,ft$ , $y = 29.080\,ft$

Step-by-step explanation:

The total area of the pool and the walkway is:

$(x + 6\,ft)\cdot (y + 6\,ft) = 950\,ft^{2}$

$(x + 6\,ft)\cdot (x + 14\,ft) = 950\,ft^{2}$

$x^{2} + 20\cdot x + 84\,ft^{2} = 950\,ft^{2}$

$x^{2} + 20\cdot x - 866\,ft^{2} = 0$

The roots of the second-order polynomial is:

$x_{1} \approx 21.080\,ft$ and $x_{2} \approx -41.081\,ft$

The only possible root is:

$x \approx 21.080\,ft$

The other dimension of the pool is:

$y = x + 8\,ft$

$y = 21.080\,ft + 8\,ft$

$y = 29.080\,ft$

What is 34% of 60000000

Ainat [17]

(Lets hope i'm right :p)

The first thing you do is make "34%" into a fraction. That would be 1/34.

After, you would multiply.

1/4 x 60000000/1 = ?

(Use cross multiply if you know)

60000000 divided by 4 = 15000000

1/1 x 15000000/1 = 15000000/1 OR 15000000

Answer: 15000000/1 or 15000000

Tell me if i'm wrong so I can prevent this in the future! Have a lovely day!
