Which is a zero of the quadratic function f(x) = 9x2 – 54x – 19?
x =
x = 3
x = 6
x = 9

step-by-step explanation:

which of the following statements correctly describes the expression below based on its degree and number of terms?

the entire expression should be subtracted from 30. to subtract the quantity, distribute the negative sign, which changes the signs on the terms. so, the –2 changes to positive and gets added to 30 instead of subtracted from it.
