(x - 7)(y - 9)

x*(y - 9) - 7*(y - 9)

x*y - x*9 - 7*y -7*(-9)

xy - 9x - 7y + 63

That's the product.

Answer: [tex]xy-9x-7y+63[/tex]

Step-by-step explanation:

The given expression: [tex] (x - 7)(y - 9)[/tex]

We know that the distributive property is given by :-

[tex]a(b+c)=ab+ac[/tex] [Left side]

[tex]OR\\\\(b+c)a=ba+ca[/tex] [Right side]

So applying the distributive property(Left sides) in the above expression, we get

[tex] (x - 7)y - (x - 7)9)[/tex]

Again applying the distributive property (Right side) in the above expression, we get

[tex]= xy - 7y- 9x +(7)(9)\\\\xy-9x-7y+63[/tex]
