Answer 1

Answer:

4xsquare+4ysquare

Step-by-step explanation:

because there are 2 x and2y for this square and ysquare

Answer 2

The equations are √x/√y = 4 and 1/x + 1/y = 1/xy

x = 16/17 and y = 1/17

The first equations supplied to us are

1) √x/√y = 4

2) 1/x + 1/y = 1/xy

The first equation is written as √(x/y) = 4

Squaring both sides, we get

x/y = 16

⇒x = 16y     ...(1)

Another expression is,

1/x + 1/y = 1/xy

⇒ (y+x)/xy = 1/xy

⇒ x+y = 1                  ...(2)

Putting the value of x from (1) in (2), we get,

16y + y = 1

⇒ 17y = 1

⇒ y = 1/17

As x = 16y

⇒ x = 16y/17
