Question

if =3+ ÷3 and xy =6,then what is of (x+y).???? please tell correctly it's my project?​

Answer 1

Answer:

35

Step-by-step explanation:

Given (x+y)=5 and xy=6

squaring on both side (x+y)-

+u (5)

a +y+2xy=25

+yry = 25 - 3ry

Now substracting 3xy in both side

+ ry = 25 -3æy

putting value of xy = 6

r +y y = 7

Now we have +y - ry = 7 and

using identity a' + b = (a + b)(a-

+ = (5)(7)

+y = 35

Thus we get answer 35
