16*18 is 288
what do u mean by "<span>I double and halve"</span>
Find common factor, in this case the common factor is 10x
So the answer would be 10x(x^6 - y^10)
I cant see the picture please take a better one and i will try to help you
There would be 2 doves and 4 parrots.
2 + 4 = the 6 in total, and the ratio between doves (2) and parrots (4) is 1 to 2 because the ratio of 2 to 4 is equal to 1 to 2.
