23 is obtuse because its highest degree angle is more than 90
24 is acute because its highest degree angle is less than 90
25 is right because it has a right angle represented by the small square symbol
Answer:
(-0)
Step-by-step explanation:

You have to find which two numbers divide number 68 and one of them has a square root that is an integer. So we have : 68 = 4 * 17 ( sqrt(4)=2)
Then sqrt(68) = sqrt(4 * 17) = sqrt(4)*sqrt(17)=2 * sqrt(17) =
=2*4.123=8.246. Rounded to the nearest hundredth it is 8.25.
This id the way you can find any square using perfect square method.
A = 3i - j - 4k
B = -2i + 4j - 3k
C = i + 2j - k
2A - B + 3C =
= 2(3i - j - 4k) - (-2i + 4j - 3k) + 3(i + 2j - k) =
= 6i - 2j - 8k + 2i - 4j + 3k + 3i + 6j - 3k =
= 6i + 2i + 3i - 2j - 4j + 6j - 8k + 3k - 3k =
= <u>1</u><u>1</u><u>i</u><u> </u><u>-</u><u> </u><u>8</u><u>k</u>
The domain is the set of 'x' values in the ordered pairs
here it is {0, 11, 17}
