Answer:
As per the condition given by you,
⇒ (x+y) (u+v) = xv+xu+yu+yv
now,
⇒ 44 × 15 = (40 + 4)(10 + 5)
and by this ,
x = 40 , y = 4 , u = 10 , v = 5
now by using the identity, i.e,
⇒ (x+y) (u+v) = xv+xu+yu+yv
⇒ (40 + 4)(10 + 5) = (40)(5) + (40)(10) + (4)(10) + (4)(5)
= 200 + 400 + 40 + 20
= 660 is the correct answer of 44 × 15
mark this as brainliast.
