Robert planted 24 daffodil bulbs and 36 tulip bulbs in his garden last winter. If all the bulbs sprout and bloom this spring, what will be the ratio of tulips to daffodils in Robert's garden? Express as a simplified ratio.

F (x) = (x + 2) (x - 6) f (x) = (x - 4) (x+3) f (x) = (x - 12) (x+1) f (x) = (x - 3) (x + 4)

Negitive 2x minus 3 equals 5 what is x equal too

What is - 54 minus - 25
