Find the LCD of the rational expression<br> Problems 3,4,5<br> Please help!!!

horrorfan [7]

The LCD of the rational expressions are 30x^5, (3x - 1)(x + 6) and (x + 3)(x + 5)^2

<h3>How to determine the LCD of the rational expressions?</h3>

<u>Expression 1</u>

The rational expressions are given as:

3/10x^2 and x + 7/15x^5

Write out the denominators

10x^2 and /15x^5

Expand each of the denominator.

10x^2 = 2 * 5 * x * x

15x^5 = 3 * 5 * x* x * x * x * x

Multiply all common factors without repetition

So, the LCD of the denominators are

LCD = 2 * 3 * 5 * x* x * x * x * x

Evaluate

LCD = 30x^5

<u>Expression 2</u>

The rational expressions are given as:

9/3x - 1 and 2x/x + 6

Write out the denominators

3x - 1 and x + 6

Expand each of the denominator.

10x^2 = 3x - 1

15x^5 = x + 6

Multiply all common factors without repetition

So, the LCD of the denominators are

LCD = (3x - 1)(x + 6)

<u>Expression 3</u>

The rational expressions are given as:

8x/(x + 5)^2 and 4x + 1/x^2 + 8x + 15

Write out the denominators

(x + 5)^2 and x^2 + 8x + 15

Expand each of the denominator.

(x + 5)^2 = (x + 5) * (x + 5)

x^2 + 8x + 15 = (x + 3) * (x + 5)

Multiply all common factors without repetition

So, the LCD of the denominators are

LCD = (x + 3) * (x + 5) * (x + 5)

LCD = (x + 3)(x + 5)^2

Hence, the LCD of the rational expressions are 30x^5, (3x - 1)(x + 6) and (x + 3)(x + 5)^2

A neighborhood development that is 4 acres is to be divided into 2/3 acre lots. How many lots can be created?

mihalych1998 [28]

6 lots can be created

<em><u>Solution:</u></em>

Given that neighborhood development that is 4 acres is to be divided into $\frac{2}{3}$ acre lots

To find: number of lots created

From given information,

Total acres = 4

one lot = $\frac{2}{3} \text{ acres }$

So number of lots created can be found by dividing the total acres by acre of 1 lot

<em><u>Thus the formula is:</u></em>

$\text{ Number of lots } = \frac{\text{ total acres }}{\text{ acre of 1 lot }}$

<em><u>Substituting the values we get,</u></em>

$\text{Number of lots } = \frac{4}{\frac{2}{3}} = 4 \times \frac{3}{2} = 6$

Thus 6 lots can be created
