I need to find x by factoring but I was absent the day we reviewed and forgot from last year: the question is: If x^2+3x = 9x -8
rosijanka [135]

x²+3x = 9x - 8

Subtract 9x on both sides

x² - 6x = -8

Add 8 on both sides

x² - 6x + 8 = 0

Now you need to find the factors of 8(numbers that multiply to equal 8) that add or subtract to -6.

Factors of 8: 1, 2, 4, 8

2 and 4 add up to 6, if they are both negative they equal -6.

(x - 2)(x - 4) = 0

x - 2 = 0

x = 2


x - 4 = 0

x = 4


x = 2, x = 4

What percent of 75 is 24?
Scilla [17]

Answer:

<h2>Your Answer is 32%</h2>

Explaination:

<em>We already have our first value 75 and the second value 24. Let's assume the unknown value is Y which answer we will find out.</em>

<em>We already have our first value 75 and the second value 24. Let's assume the unknown value is Y which answer we will find out.As we have all the required values we need, Now we can put them in a simple mathematical formula as below:</em>

<em><u>STEP 1 </u>>> Y = <u>2</u><u>4</u></em>

<em> </em><em> </em><em> </em><em> </em><em> </em><em>75</em>

<em><u>STEP 2</u> >> </em><em> </em>

<em> </em>

<em><u>24</u><u> </u> × <u>10</u><u>0</u></em><em> </em><em> </em><em> </em><em> </em><em>=</em><em> </em><em> </em><u><em>3</em><em>2</em></u>

<em>7</em><em>5</em><em> </em><em> </em><em>× 100</em><em> </em><em> </em><em> </em><em> </em><em> </em><em> </em><em> </em><em>1</em><em>0</em><em>0</em>

<em><u>STEP 3</u>>> Y = 32</em><em>%</em>

<em>Finally, we have found the value of Y which is 32 and that is our answer.</em>

<em>You can use a calculator to find what percent of 75 is 24, just enter 24 ÷ 75 × 100 and you will get your answer which is 32</em><em>.</em>
