Answer: 4x+18=24

First move 18 to other side (24-18), left with 4x=6

Divide both sides by 4 to be left with x=6/4 & reduce that fraction down to 3/2

Step-by-step explanation:

One number is 8 more than another number, and their sum is 20. Find the numbers.

melomori [17]

Answer:

First number=6

Second number=14

Step-by-step explanation:

Let the first number be x

So the second number is x+8

So the sum of the two is

X+x+8=20

2x+8=20

2x=20-8

2x=12

X=12/2

The second number will x+8

So 6+8=14

First number=6

Second number=14

Solve 16(3x-5) -10(4x-8) = 40

Mashcka [7]

Answer:

x = 5

Step-by-step explanation:

<u>Step 1: Multiply out the brackets</u>

48x - 80 - 40x + 80 = 40 → <em>negative + negative = positive [-10 x -8]</em>

<u>Step 2: Simplify</u>

8x = 40 →<em> collect like terms</em>

<u>Step 3: Solve</u>

x = $\frac{40}{8}$

x = 5

Which statement shows how the product of (x + 7)2 demonstrates the closure property of multiplication?

Illusion [34]

The true statement that show the closure property of multiplication :

<h3>a. x² + 14x + 49 is a polynomial</h3>

$\texttt{ }$

<h3>Further explanation</h3>

<em>If equation ax³ + bx² + cx + d = 0 has roots x₁ , x₂ , and x₃ then</em>

$x_1 + x_2 + x_3 = - \frac{b}{a}$

$x_1 x_2 + x_1 x_3 + x_2 x_3 = \frac{c}{a}$

$x_1 x_2 x_3 = - \frac{d}{a}$

Let us now tackle the problem!

$\texttt{ }$

This problem is about Polynomial.

$(x + 7)^2 = (x + 7)(x + 7)$

$(x + 7)^2 = x^2 + 7x + 7x + 7(7)$

$(x + 7)^2 = x^2 + 14x + 49$

$x^2 + 14x + 49$ is a polynomial.

$x + 7$ is polynomial.

It demonstrates the closure property of multiplication.
