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 two numbers have a sum of 217 and a <br> difference of 85?

Setler [38]

Answer:

the two numbers are 151 and 66

Step-by-step explanation:

x+y =217

x-y = 85

add the two equations

x+y =217

x-y = 85

-------------

2x = 302

divide by 2

2x/2 = 302/2

x = 151

now find y

x+y =217

151+y =217

subtract 151 from each side

y = 217-151

y =66
