Answer:
Step-by-step explanation:
Simplify the numerator:
Rewrite 4 as 
Rewrite 
as 
Since both terms are perfect squares, factor using the difference of squares formula, 
and b = 5x.
Multiply 5 by -1.
Simplify the denominator:
Subtract x from -11x
Factor 2x out of 
+ <span>200g of 10% sugar solution: there is 200*10%= 20 g
+ </span><span>300g of 20% sugar solution: 300*20%= 60 g
The total of sugar: 20+60= 80g
And The </span><span>concentration is 80:(200+300)= 80:500= 16%

Start by finding the area of one of the stools with this formula:
A=(3.14)(12)(12)
Then multiply that answer by five, since there are 5 stools.
Hope this helps :) good luck
Expanded: 3x^2 + 17x +10
Simply: it’s already simplified
