Which is a factor of 28xy - 154x + 20y - 110?
x - 4, 7x + 4, 7x - 11, 2y - 11

Solution:

Given expression 28xy - 154x + 20y - 110

In order to find factors,we need to split the given expression

28xy - 154x + 20y - 110 = 7x(4y -22) + 5(4y - 22)

28xy - 154x + 20y - 110 = (7x + 5)(4y - 22)

28xy - 154x + 20y - 110 = 2(7x + 5)(2y - 11)

The factors are 2(7x + 5) and (2y - 11)

Which is a factor of 28xy - 154x + 20y - 110?

Summary:

The factor of 28xy - 154x + 20y - 110 is 2y - 11
