Both sides of the equation are squared.

[tex]\dfrac{x-12}{4}=\sqrt{x} \qquad\text{given}\\\\ \left(\dfrac{x-12}{4}\right)^2=x \qquad\text{square both sides}\\\\ \left(\dfrac{x}{4}-3\right)^2=x \qquad\text{divide out the fraction}\\\\ \dfrac{x^2}{4^2}-\dfrac{6}{4}x+9=x \qquad\text{$(a-b)^2=a^2-2ab+b^2$}\\\\\dfrac{x^2}{16}-\dfrac{5x}{2}+9=0 \qquad\text{subtract $x$}[/tex]

Can someone please help me understand how to expand 8(3y-4). Please give a detailed explanation.

Answers

Answer:

24y - 32

Step-by-step explanation:

You take the 8 and multiply each term by in the parentheses by 8, so

8(3y - 4) becomes 8 * 3y - 8 * 4 = 24y - 32

Answer:

well, you can multiply them, to simplify the equation, but to expand, try adding or multiplying 2 multiples of 8, in the middle the 4 can change by adding 2+2 or 3+1. For 3y, you can do 3*y.

What single percentage change is equivalent to a 18% increase followed by a 13% decrease?

Answers

Given:

18% increase followed by a 13% decrease.

To find:

The single percentage equivalent to a 18% increase followed by a 13% decrease.

Solution:

Let a number be 100.

If it is increased by 18% then the number becomes

[tex]Number=100+\dfrac{18}{100}\times 100[/tex]

[tex]=100+18[/tex]

[tex]=118[/tex]

Then, it is decreased by 13%.

[tex]Number=118-\dfrac{13}{100}\times 118[/tex]

[tex]=118-15.34[/tex]

[tex]=102.66[/tex]

New number is 102.66.

Now, the percentage change is

[tex]\%\text{ Change}=\dfrac{\text{New number - Initial number}}{\text{Initial number}}\times 100[/tex]

[tex]\%\text{ Change}=\dfrac{102.66-100}{100}\times 100[/tex]

[tex]\%\text{ Change}=\dfrac{2.66}{100}\times 100[/tex]

[tex]\%\text{ Change}=2.66\%[/tex]

Therefore, the Single percentage change is 2.66%.
