If one factor of 21xy^3-15x^2y^2 is 3xy^2, what is the other factor

The other factor = 7y - 5x

Step-by-step explanation:

If one factor of 21xy^3-15x^2y^2 is 3xy^2, other factor will be achieved by dividing the expression by the known factor

21xy^3-15x^2y^2 ÷ 3xy^2

Factorise the numerator

3xy^2( 7y - 5x )/3xy^2

3xy^2 will cancel each other

The other factor = 7y - 5x

30 feet

step-by-step explanation:

that would be 2 1/2 * 12

= 24 + 6

= 30 feet   (answer)
