Answer:
Step-by-step explanation:
You would square 3968 and subtract 1.
The solution is 2sqrt77/77. You just fill in 2/3 for the x's. When you do that, you do that you get (2/3)/sqrt(9-[2/3]^2) which, simplified, is (2/3)/sqrt(9-[4/9]). Now use the common denominator under the radical of 9 to get (2/3)/sqrt([81-4]\9). Simplifying even further gives you (2/3)/([sqrt(77)]/3). Now do that division by multiplying 2/3 by the reciprocal of ([sqrt(77)]/3) to get 2/sqrt77. I rationalized the denominator to get that result up there.
1 foot and 6 inches is the answer. Subtract the highest from the lowest #.
Answer: If this isnt wrong then I probably forgot how to do this... You plug in 10 with 10^2. so then you'll get 100 time pi and youll get 314.159265.
