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:
i) \frac{3}{5} + (- \frac{1}{2}) = \frac{6}{10} - \frac{5}{10} = \frac{1}{10}
ii) 4^{3} + 8^{2} + \sqrt{9}
iii) (\frac{4}{5})^{2}. \sqrt[3]{8} \leqx^{3} - 3x + 6 \leq \sqrt{\frac{1}{3}}
Step-by-step explanation:
i) \frac{3}{5} + (- \frac{1}{2}) = \frac{6}{10} - \frac{5}{10} = \frac{1}{10}
ii) 4^{3} + 8^{2} + \sqrt{9}
iii) (\frac{4}{5})^{2}. \sqrt[3]{8} \leqx^{3} - 3x + 6 \leq \sqrt{\frac{1}{3}}
The answer is 35 because that's not a multiple of 8
Answer:
Marcus invited 40 and Laticia invited 28
Step-by-step explanation:
x+y=68 x+40=68
x=y-12 -40 -40
y-12+y=68 x=28
2y-12=68
+12 +12
2y=80
2 2
y=40
