Answer:
2 x 3 x 7
Step-by-step explanation:
Thats the answer I'm not guessing but I dont know how to explain thourghly.
The best i can explain it would be that A the numbers can't be divided further. In C 14b can be therefore it isnt C its A! ( B and D dont equal 42)

We can expect about 193 earthquakes.
Hope this helps.
Answer:
all x intercepts [-4, 0] [4, 0]
Step-by-step explanation:
x-intercept, i.e. y=0
f(x) = x^3 - 4x^2 - 16x + 64 = 0
(x^3 + 4^3) - 4x^2 - 16x = 0 [FYI, x^3 + y^3 = (x + y)(x^2 - xy + y^2)]
(x + 4)(x^2 - 4x + 16) - 4x^2 - 16x = 0
(x + 4)(x^2 - 4x + 16) - 4x(x + 4) = 0
(x + 4)(x^2 - 4x + 16 - 4x) = 0
(x + 4)(x^2 - 8x + 16) = 0
(x + 4)(x - 4)^2 = 0
x = -4 or 4
all x intercepts [-4, 0] [4, 0]
