Answer: 17.46
Step-by-step explanation:
X^2 = 7^2 + 16^2 = 49 + 256
X^2 = 305
X = sqrt(305)
X = 17.46
Answer:
{0, 4 and -3}
Step-by-step explanation:
f(x)=x^3-x^2-12x can be factored, starting by taking out the 'x' factor:
f(x)=x^3-x^2-12x = x(x^2 - x - 12), and then by factoring the quadratic:
f(x) = x(x - 4)(x + 3) = 0
Then the zeros are {0, 4 and -3}.
