(x³ + ³) / (x - y)<br> Do not include parentheses in your answer.

Lubov Fominskaja [6]

The simplified expression of $\frac{x^3 + (-y)^3}{(x - y}$ is $x^2+xy+y^2$

<h3>Complete question</h3>

Simplify the expression: (x³ + (-y)³) / (x - y)

Do not include parentheses in your answer.

<h3>How to simplify the expression?</h3>

The expression is given as:

$\frac{x^3 + (-y)^3}{(x - y}$

Open the inner bracket

$\frac{x^3 -y^3}{(x - y}$

Apply the difference of two cubes to the numerator

$\frac{(x-y)(x^2+xy+y^2)}{(x - y}$

Cancel out the common factors

$x^2+xy+y^2$

Hence, the simplified expression of $\frac{x^3 + (-y)^3}{(x - y}$ is $x^2+xy+y^2$

Sonbull [250]

The sample space for this action of selecting crispy crust (C) or deep crust (D) by two persons are (C, C)(C, D)(D, C)(D, D).

<h3>What is a sample?</h3>

A sample is the collection of well-defined elements. A sample is represented by a capital letter symbol and the number of elements in the finite set is shown as curly bracket {..}.

At a pizza shop, customers can select either crispy crust (C) or deep crust (D).

Suppose that two customers place an order and select their crust.

The number of samples will be

Sample size = 2 × 2

Sample size = 4

The combination of the sample will be

Sample = (C, C)(C, D)(D, C)(D, D)

The sample space for this action of selecting crispy crust (C) or deep crust (D) by two persons are (C, C)(C, D)(D, C)(D, D).

Answer the photo below <br> **Explain how you got it**

lbvjy [14]

Answer:

38 square inches.

Step-by-step explanation:

First, the figure must be broken down into two shapes to solve for the area. The easiest way to do this is through a triangle and a rectangle.

This leaves a rectangle with a height of 8 in and a width of 4 in, as well as a triangle with a slant of 5 in, a base of 4 in, and height of 3 in.

Then, solve for the area of the two shapes.

Rectangle:

Area = L x W

4 x 8

= 32 inches squared.

Triangle:

Area = (1/2)(B x H)

(1/2)(4 x 3)

(1/2)(12)

= 6 inches squared.

Add these two values for a total area of 38 square inches.
