This would be.
-23√6 all over 6.
Or: around -9.39
The answer would be C. both plane A and B because it's on line s which lies on both planes.
1 pound = 16 ounces
multiply the amount of pounds you have by 16 (that's how many ounces is in a pound) your answer should be whatever you get
example: you have 13 pounds, just multiply it by 16, the answer is 208.
so there are 208 ounces in 13 pounds.
or you could go google and ask them.
hope this helps.
2.5 *(10)+15=40
I guess this is the answer :)
