If x2 + y2 = 38 and x - y = 2, then what is x? If there are two possible answers, then enter the larger of the two.

Ket [755]

If x-y=2 then x=2+y

And if you insert that in the first equation

$(2 + y) {}^{2} + y {}^{2} = 38$
$4 + 4y + y {}^{2} + {y}^{2} = 38$
$2y {}^{2} + 4y - 34 = 0$
$y = - 1 + \sqrt{17}$
Or
$y = - 1 - \sqrt{17}$

The first one is bigger so the answer is

$y = - 1 - \sqrt{17}$

4(2x+3)+4(3x+2) simplify and expand answer

timama [110]

Answer:

20x + 20

Step-by-step explanation:

4 ( 2x + 3 ) + 4 ( 3x + 2 )

Take 4 common from both,

4 ( 2x + 3 + 3x + 2 )

= 4 ( 2x + 3x + 3 + 2 )

= 4 ( 5x + 5 )

= 4 ( 5x ) + 4 ( 5 )

= 20x + 20
