f(x) = x^3 + 5x^2 - 4x - 20
The zeros of the polynomial function: x^3 + 5x^2 - 4x - 20 = 0
x^3 + 5x^2 - 4x - 20 = 0
x^2(x + 5) - 4(x + 5) = 0
(x^2 - 4)(x + 5) = 0
(x + 2)(x - 2)(x + 5) = 0
(x + 2) = 0; x = -2
(x - 2) = 0; x = 2
(x + 5) = 0; x = -5
Answer is the first one
x = -5, x = -2, x = 2
First find the volume of the cylinder v = pi* r^2 * h
Then find the volume of the cone V = 1/3 * pi* r^2 * h
Then compare your two numbers.
Answer:b
Step-by-step explanation:9 multiply 8 multiply 6
Answer:
Three places to the left
Step-by-step explanation:
It would be moved to the left because 407.26 is being divided by 1000, not multiplied. It would be 3 because there are three zeroes in 1000.
15x-6

21x/2+3. Multiply everything by 2: 30x-12=21x+6. Combine like terms: 9x=18. Get the unknown by itself: 9x/9=X. 18/9=2. X is less than or equal to 2 :)
