Solve the following equation: x^3+3x^2-10x=0

1 answer:

5 0

X³ + 3x² - 10x = 0
The GCM of those three terms is x. So group them by x.

x(x² + 3x - 10) = 0
factor x² + 3x - 10
x(x - 2)(x + 5) = 0

x = 0 , x = 2 , x = -5

Answer:

$\frac{2}{3}$

Step-by-step explanation:

Sum the frequency column to find the total number of students

total = 2 + 9 + 5 + 5 + 3 = 24

number of students finished in less than 20 mins = 2 + 9 + 5 = 16

fraction of students = $\frac{16}{24}$ = $\frac{2}{3}$

Multiply the rate per mile by the miles and the appropriate conversion factor.

$\dfrac{1.2\,\text{oz}}{1\,\text{mi}}\cdot (15\,\text{mi})\times \dfrac{1\,\text{cup}}{8\,\text{oz}}=\dfrac{1.2\cdot 15}{8}\,\text{cup}=2.25\,\text{cup}$
