Julie makes $7.65 for 1 hour. We know she earned $24.48 so how many hours did she work to earn that? you could set it up like this

<u>1hr</u>    =    <u>X (hrs)</u>
$7.65       $24.48  (money earned)    now cross multipy

7.65 * x = 1*24.48
7.65x=24.48  (now we want x alone)

<u>7.65x</u>=<u>24.48 </u> (you must divide both sides by 7.65 to get x alone)
7.65     7.65
now any number divided by itself is 1 so 
1x is automatically written like this 

x=<u>24.48</u>
      7.65    now divide 24.48 by 7.65 to get the answer
x=3.2 hours that's your answer. She worked 3.2 hours to earn $24.48

(5x+1)(5x-1) combine terms
Alinara [238K]

Answer:

25x^2 -1

Step-by-step explanation:

If you multiply parentheses:

(5x*5x) + (5x*-1) + (1*5x) + (1*-1)

25x^2 - 5x + 5x -1

25x^2 -1

A simpler way is to memorize this formula

(Square1 - square2)= (sqrt of square1- sqrt of square2)*(sqrt of square1 + sqrt of sqaure2)
