They're the same like integers.
First you should interpret it.
For example:
a. -3x + 8x is the same like -3 + 8. You just add x.
Which is 5x.

PolarNik [594]

$a\cdot b=(7)(4)+(3)(-1)=25\\\\|a|=\sqrt{7^{2}+3^{2}}=\sqrt{58}\\\\|b|=\sqrt{4^{2}+(-1)^{2}}=\sqrt{17}\\\\\cos \theta=\frac{25}{\sqrt{58}\sqrt{17}}\\\\\theta=\cos^{-1} \left(\frac{25}{\sqrt{58}\sqrt{17}} \right) \approx 37.235^{\circ}$

Find the least common denominator (LCD) of 7/9 and 5/6

AnnZ [28]

Answer: 18

Step-by-step explanation:

The least common denominator of $\frac{7}{9}$ and $\frac{5}{6}$ is going to be a multiple of 9 and 6. Let us list them out:

9: 9, 18, 27, 36, 45, 54, 63, 72, 81, 90

6: 6, 12, 18, 24, 30, 36, 42, 28, 54, 60

You can see I bolded and underlined 18. Why? This is the first common multiple of 9 and 6 so it is our least common denominator (LCD).

Who ever gets this wright first gets a thanks!!! :D

klasskru [66]

The sequence is subtracting 5.5 each time:

19 - 5.5 = 13.5

30 - 5.5 = 24.5

24.5 - 5.5 = 19

so 24.5, or 24 1/2 is your answer

hope this helps
