Complete the table below to show the differences between algebraic

expression and equation.

Describe each to show their differences.

Give 3 examples of each.

Answer:

Explained below with examples

Step-by-step explanation:

1. Algebraic expression in mathematics are basically expressions that are formed from variables, integer constants, and also algebraic operations.

Examples include;

>> 2x² − xy

>> 3ab + 2b²

>> x² + y²

2. An algebraic equation is a phrase where the two sides of the equation which are the left and right hand sides are connected by the equal to sign (=).

Examples are;

>> 3y - y² = 2y² + 2

>> 3x - 4y = x + 2

>> 5a + 3b = 2b - 1

A polynomial is factored using algebra tiles. Which polynomial was factored?

alexdok [17]

The algebra tiles shows the polynomial x² - 2x - 8

<h3>Polynomial</h3>

Polynomial is an expression that involves only the operations of addition, subtraction, multiplication of variables.

Algebra tiles are square and rectangle shaped tiles or tiles that represent numbers and variables.

From the image:

Polynomial = x² + x + x - x - x - x - 1 - 1 - 1 - 1 - 1 - 1 - 1 - 1 = x² - 2x - 8

The algebra tiles shows the polynomial x² - 2x - 8

What does X equal. -356 = -77 -9x This is grade 7 math.

LuckyWell [14K]

Answer:

<h2> x = 2.82 (approx.)</h2>

Step-by-step explanation:

Given, 

- 356 = -77 - 99x

=> -77 - 99x = -356

=> -99x = -356 + 77

=> -99x = -279

$= > x = \frac{ - 279}{ - 99}$

=> x = 2.8181....

=> x = 2.82 (approx.) (Ans)

Two decimals numbers, to the thousandths, that have a sum of about 5 and a difference of about 3. Then do the math to prove it w

mina [271]

Answer:

The numbers are approximately: 4.000 and 1.000

Step-by-step explanation:

The given parameters can be expressed as:

$\frac{x}{1000} + \frac{y}{1000} \approx 5$

$\frac{x}{1000} - \frac{y}{1000} \approx 3$

Required

Determine the numbers

In each of the equations, multiply by 1000

$1000 * [\frac{x}{1000} + \frac{y}{1000} \approx 5]$

$x + y \approx 5000$

$1000 * [\frac{x}{1000} - \frac{y}{1000} \approx 3]$

$x-y \approx 3000$

So, we have:

$x + y \approx 5000$

$x-y \approx 3000$

Add the two equations

$x + x + y - y \approx 5000 + 3000$

$2x \approx 8000$

Solve for x

$x \approx 8000/2$

$x \approx 4000$

Substitute $x \approx 4000$ in $x + y \approx 5000$

$4000 + y \approx 5000$

$y \approx 5000 - 4000$

$y \approx 1000$

Using:

$\frac{x}{1000} + \frac{y}{1000} \approx 5$

We have:

$\frac{4000}{1000} + \frac{1000}{1000} \approx 5$

$4.000 + 1.000 \approx5$

This implies that, the numbers approximates to 4.000 and 1.000, respectively.

3x^2-3x ----------- -3 x^2-9x please give me the simplified answer + explanation

STatiana [176]

You want us to simplify $\frac{3x^2-3x}{x^2-9x}-3$

first, factor top and bottom
$3x^2-3x=3x(x-1)$
$x^2-9x=x(x-9)$

so we have
$\frac{3x(x-1)}{x(x-9)}-3=$
$\frac{3(x-1)}{x-9}-3$
we want to combine fractions so multiply 3 by $\frac{x-9}{x-9}$
$\frac{3(x-1)}{x-9}-\frac{3(x-9)}{x-9}=$
$\frac{3(x-1)-3(x-9)}{x-9}=$
$\frac{3x-3-3x+27}{x-9}=$
$\frac{24}{x-9}$

the simplified answer is $\frac{24}{x-9}$
