Isolate the variable by dividing each side by factors that don't contain the variable.
a=- \frac{ x^{2}- \sqrt{( x^{3} + x^{2} b+12x-72(x-2)-2x} }{x-2} ,- \frac{ x^{2}+ \sqrt{( x^{3} + x^{2} b+12x-72(x-2)-2x} }{x-2}
Solve for b by simplifying both sides of the equation then isolating the variable.
b= \frac{12}{x}+ \frac{72}{ x^{2} }-2+2a- \frac{4a}{x}+ \frac{ a^{2} }{x}- \frac{2a^{z} }{ x^{2} }
Hopefully i helped ^.^ Mark brainly if possible. Lol once again i saw the same question so why not answer it again!
114
1) Gathering the data
The mean is calculated by adding all the numbers and divided by the number of observations in this case 5.
So, Laura needs to score 114 to get at least 94 as an average.

Answer:
$1.60
Step-by-step explanation:
<em><u>Write out a proportion. </u></em>
5 bananas/$2 = 4 bananas/$x
<em><u>Simplify the proportion, by cross multiplying. </u></em>
2 times 4 equals 8, then divide 8 by 5, which will give you our variable x.
8/5 is the same as 1.60, so the cost of 4 bananas will cost $1.60.
Hope this helped,
