Yes they are both equivalents because they are whole's and some examples would be 8/8,9/9,4/4. and 5/5 because they are all whole's 7 out of 7 pieces of pizza is the whole pizza.

∛(1/8 - x) = -1/2

Take the 3rd power of both sides and solve:

(∛(1/8 - x))³ = (-1/2)³

1/8 - x = -1/8

2/8 = x

x = 1/4

Use the zero product property to find the solutions to the equation x^2-15x-100=0

7nadin3 [17]

Answer:

$x = 20$ or $x = -5$

Step-by-step explanation:

To solve the quadratic equation we must factor the expression

Look for 2 numbers that when you multiply them, obtain the result -100 and when you add them, obtain the result -15.

You can verify that these numbers are -20 and 5

$-20 +5 = -15\\\\-20 * 5 = -100$

Then the polynomial factors are

$(x-20) (x + 5) = 0$

The zero product property says that if two terms $a * b = 0$ then

$a = 0$ or $b = 0$

$(x-20) = 0$ or $(x + 5) = 0$

$x = 20$ or $x = -5$
