Answer:
222 = score in 2nd game
Step-by-step explanation:
Let x = score in 1st game
3/4(x) + 30 = score in 2nd game
x + 3/4(x) + 30 = 478 Multiply thru by 4 to eliminate the fraction
4x + 3x + 120 = 1912
7x + 120 = 1912
7x = 1792
x = 256
3/4(x) + 30 = 3/4(256) + 30
= 192 + 30
222 = score in 2nd game
Check: 222 + 256 = 478
The power of two is any number squared.
Example~ 3*3, 5*5, 8*8
12 1/5
Step-by-step explanation: 7 + 5 =12 andd then add the one 5

Step-by-step explanation:</h3>
<u>How can </u><u>we</u><u> factor 5x^2 + 26x - 24 = 0 using the completing the square </u><u>method?</u>
Let's solve your equation step-by-step.
![\bold{Given \: Equation: \color{brown} 5x²+26x-24=0}](https://tex.z-dn.net/?f=%20%5Cbold%7BGiven%20%5C%3A%20%20Equation%3A%20%5Ccolor%7Bbrown%7D%205x%C2%B2%2B26x-24%3D0%7D)
First, add 24 to both sides.
Since the coefficient of 5x² is 5, divide both sides by 5.
The coefficient of 26/5x is 26/5. So, let b=26/5.
Then we need to add (b/2)²=169/25 to both sides to complete the square.
Add 169/25 to both sides.
Factor the left side.
Take square root.
Then, add (-13)/5 to both sides.
