Question

If AB = 3xy + 7x²y and BC = -4x²y + 13xy, then find AB + BC

a. 4x²y + 16xy

b. -3x²y + 16xy

c. 3x²y + 16xy

d. None of these

​

Answer 1

Answer:

option c,

AB+BC=3xy+7x^2y-4x^2y+13xy,

=3x^2y+16xy

Answer 2

Answer:

OPTION C IS THE RIGHT ANSWER..

Step-by-step explanation:

GIVEN,

AB=3xy+7x^2y AND

BC =-4x^2y+13xy...

SO,

AB+BC = (3xy+7x^2y) +(-4x^2y +13xy)

= 3x^2y+16xy
