It would be 76 degrees because it’s a vertical angle
Sqrt(486) - sqrt(24) + sqrt(6)
find the factors of 486 that we can remove from under the square root sign
2 * 243
2 * 3 * 81
2 * 3 * 9 * 9 (we have 2 nines, we can move a 9 outside the sqrt sign)
sqrt(486) = 9 sqrt(6)
Repeating for sqrt(24)
2 * 12
2 * 2 * 6
2 * 2 * 2 * 3 (we can move a 2 outside the sqrt
sqrt(24) = 2 sqrt(6)
Finally, add all 3 terms together
9 sqrt(6) - 2 sqrt(6) + sqrt(6)
8 sqrt(6)
8 times square root of 6 is the final answer
<em><u>Answer:</u></em>
I'm assuming this is a <em>combining like terms</em> question, in which case the answer would be 6n - 3c.
<u><em>Step-by-step explanation:</em></u>
I'm guessing your teacher wants you to combine the like terms, and 1n plus 5n = 6n, minus 3c is the answer, which is 6n - 3c. If your teacher wanted you to solve for each variable, you can't do that because you don't have enough information, and there's an infinite number of solutions.

Answer:
-21/35
Step-by-step explanation:
So, 7/5 is a postive number, since it doesn't have a negative - sign in front of it. On the other hand, -21/35 does. Knowing this, we can conclude that -21/35 is smaller than 7/5.
If you want another way of thinking about it, just guessing, what is 7/5? Well, 7 is bigger than 5, so it must be at least 1. On the other hand, with -21/35, the -21 doesnt look like its bigger than 35, so it must be smaller than 1.
Answer:
<u>-21/35 is smaller than 7/5 </u>

Use the identity:-
a^2 + b^2 = (a + b)^2 - 2ab
Plugging in the given values;-
a^2 + b^2 = 6^2 - 2*7 = 36-14 = 22 Answer
