First you have to put like terms together:
bf+af+be+ae
Now you factor the first two terms and then the two last terms:
f(b+a)+e(b+a)
Now you factor even further. By putting what is in parentheses by what is outside the parentheses:
(b+a)(f+e)
What you got is correct as mine is too. I hope this formula helps for future problems:
ax+bx+ac+bc=x(a+b)+c(a+b)
=(a+b)(x+c)
Answer:
x = 18
Step-by-step explanation:
Given
3 +
= 
Multiply through by the LCM of 2 and 3 to clear the fractions.
The LCM of 2 and 3 is 6, thus
18 + 2x = 3x ( subtract 2x from both sides )
18 = x
The answer is 604.235378543
First, you need to find the trend line that you are going to use before you can answer question 9 and 10.
To do that select 2 points from your list and find the y = mx + b equation.
After you have your equation, all you need to do is plug in the values that you are given for x. Evaluate the expression and you will have your answer.
Very hard question. .....
