Answer:

You have $10.600 Canadian dollars to spend.

Step-by-step explanation:

This problem can be solved by a rule of three.

In a rule of three problem, the first step is identifying the measures and how they are related, if their relationship is direct of inverse.

When the relationship between the measures is direct, as the value of one measure increases, the value of the other measure is going to increase too.

When the relationship between the measures is inverse, as the value of one measure increases, the value of the other measure will decrease.

In this problem, we have the following measures:

-The number of US dollars

-The number of Canadian dollars.

As the number of US dollars increases, so does the number of Canadian dollars, which means that the relationship between the measures is direct.

The problem states that $1 US dollar is $1.06 Canadian dollars. The problme wants to know how much $10000 is in Canadian dollars. So:

1 - 1.06

10000 - x

x = 10000*1.06

x = $10.600

You have $10.600 Canadian dollars to spend.

How do you simplify this?
timama [110]
Notice how the top is an addition of two cubes, namely x and 2.

You can rewrite the equation as:

\frac{x^{3} + 2^{3}}{x + 2}

Now, (a + b)³ can be simplified down to (a + b)(a² - ab + b²)
Following the same pattern, we get:

\frac{(x + 2)(x^{2} - 2x + 4)}{x + 2}
= x^{2} - 2x + 4
