The LCD is 6. Multiply the entire expression by 6, and then divide the result by 6:
6 [ <span>6(x^2-1) * 6x-1/6(x+1) ]
------------------------------------
6
When expanded and simplified, we get:
(36x^2 - 36)*6x - (x+1)
-------------------------------
6
or:
216x^3 - 216x - x - 1
----------------------------
6
Combining the two x-terms:
216x^3 - 217x -1
----------------------- (answer)

Answer:
The answer is 152.5 ft
Step-by-step explanation:
What I did as multiply 6x2.5 and didn't divide by 2 because there are 2 of those triangles and got 15
Then I multiplied 6.5x11 and added that to 6x11 and got 137.5
After that I added 137.5 and 15 to get my answer of 152.5
Answer:
The total change in his account is of -$85, that is, a loss of $85
Step-by-step explanation:
We combine these changes. So
On Tuesday, he withdrew $90 from his account, which means that, the total change, initially of $0, is now of -$90.
On Thusday, he deposited $20, which means that the total change of -$90 is now of -$90 + $20 = -$70
On Friday, he wrote a check of $15, removing 15 from his account, which means the total change will be of -$70 -$15 = -$85
