If f(x) is = to 0 then that means that you would have to plug the 0 in for all of the x that are in the function and the solve it.
f(x)= x3-4x-1
f(0)= (0)3-4(0)-1
0 0 0 -1
-1
so that means that -1 would be the answer for the function
Multiply the length and the width giving you 180
Answer:
Step-by-step explanation:
Given points are: (-4,2) and (5,6)

6x-6=8x
subtract 6x from both sides
-6=2x
divide both sides by 2
x= -3
3 nickles plus 8 pennies
(3x5)+(8x1) = 15 + 8 = 23
= 23¢
