Answer:

x = -1 or x = -y

Step-by-step explanation:

Solve for x:

(x + 1) (x^2 + 2 x y + y^2) = 0

Split into two equations:

x + 1 = 0 or x^2 + 2 x y + y^2 = 0

Subtract 1 from both sides:

x = -1 or x^2 + 2 x y + y^2 = 0

Write the left hand side as a square:

x = -1 or (x + y)^2 = 0

Take the square root of both sides:

x = -1 or x + y = 0

Subtract y from both sides:

Answer: x = -1 or x = -y

A business is owned by 3 people. Mrs. Applegate owns

Bezzdna [24]

Given:

Mrs. Applegate owns $\dfrac{3}{19}$ of the business.

Mrs. Brown owns 3 times as much as Mrs. Charles.

To find:

The fractional part of the business that Mrs. Brown owns.

Solution:

Let Mrs. Charles owns x part of business.

Mrs. Brown owns 3 times as much as Mrs. Charles.

Mrs. Brown owns = 3x part of business.

Mrs. Applegate owns $=\dfrac{3}{19}$ of the business.

$x+3x+\dfrac{3}{19}=1$

$4x=1-\dfrac{3}{19}$

$4x=\dfrac{19-3}{19}$

$4x=\dfrac{16}{19}$

Divide both sides by 4.

$x=\dfrac{16}{4\times 19}$

$x=\dfrac{4}{19}$

Now,

Mrs. Brown owns $=3\times x$

$=3\times \dfrac{4}{19}$

$=\dfrac{12}{19}$

Therefore, Mrs. Brown owns $\dfrac{12}{19}$ of the business.
