twenty minus the product of 4 and a number x is less than four.

how is this equation written?

(x-y)x^2-12xy+20y^2)

the answer I came up with is: (x-y)x^2-12xy+20y^2)

"twenty minus the product of 4 and a number x is less than four" and you came up with "(x-y)x^2-12xy+20y^2)"??
you can't be serious, that equation must be for a different problem.

lets work it out
twenty
20
the product of 4 and a number x
4x
twenty minus the product of 4 and a number x
20-4x
twenty minus the product of 4 and a number x is less than four
20-4x<4
