Question

If the number x is 3 less than the number y and the sum of the squares of x and y is 29,find the product of x and y​

Answer 1

Answer:

x=y-3

y=x+3............(i)

y²+x²=29

(x+3)²+x²=29

2x²+6x+9=29

x²+3x-10=0

(x+5)(x-2)=0

x= -5. x= 2

y=x+3

Hence,

y= -2. y= 5

x•y=10

Step-by-step explanation:

Answer 2

Answer:

$y$ +  $y$  - 3 = 29           $x$ = $y$ -3

2 $y$ = 32

 $y$ = 32/2

$y$ = 16

  $x$ = y - 3

    = 16 - 3 = 13

 $y$  = 16    $x$ = 13

 $x$$y$  = 16 x 13

       =208
