pablo has $4200 to invest. pablo's goal is to have $5000 after 4 years. is this possible if he invests with a rate of return of

Ivenika [448]

4200 * 1.06 = 4452.
4452 * 1.06 = 4719.12.
4719.12 * 1.06 = 5002.27

It would only take 3 years to reach $5000.

−(7 − 2x) + 7 = −7 solve for x

jekas [21]

First, remove the parentheses

-7+2x+7=-7

Cancel the equal terms.

2x+7=0

Subtract 7

2x= -7

Divide both sides by 2

Final answer is:

X= -3.5

Which of the following is the product of the rational expression shown below

wolverine [178]

Option C: $\frac{x^{2}-9}{x^{2}-4}$ is the product of the rational expression.

Explanation:

The given rational expression is $\frac{x+3}{x+2} \cdot \frac{x-3}{x-2}$

We need to determine the product of the rational expression.

<u>Product of the rational expression:</u>

Let us multiply the rational expression to determine the product of the rational expression.

Thus, we have;

$\frac{(x+3)(x-3)}{(x+2)(x-2)}$

Let us use the identity $(a+b)(a-b)=a^2-b^2$ in the above expression.

Thus, we get;

$\frac{x^{2} -3^2}{x^{2} -2^2}$

Simplifying the terms, we get;

$\frac{x^{2}-9}{x^{2}-4}$

Thus, the product of the rational expression is $\frac{x^{2}-9}{x^{2}-4}$

Hence, Option C is the correct answer.
