Answer:
see explanation
Step-by-step explanation:
We require 2 equations with the recurring part after the decimal point.
Let x = 0.555..... → (1)
Multiply both sides by 10, then
10x = 5.555..... → (2)
Subtract (1) from (2) thus eliminating the recurring decimal
(10x - x) = (5.5555 - 0.5555 ), that is
9x = 5 ( divide both sides by 9 )
x = 
I like to change all the subtraction to addition of the negative.
4x^2 + 8x + (-11x) + 6 + (-5x^2) + 2
Now combine the like terms.
-x^2 -3x + 8
Your answer is A: -x^2 - 3x + 8

Step-by-step explanation:
4x^2+25x+6
(4x+1)(x+6)
Hope this helps!
45+55= 100 not multiply by 3 and you get 300.
Dividing the sum by the number of items to find the mean. ... The formula to find the sample mean is: = ( Σ xi ) / n. All that formula is saying is add up all of the numbers in your data set ( Σ means “add up” and xi means “all the numbers in the data set).
I feel bad because I think maybe you forgot to put the picture, So here’s the definition of mean
