The answer is 13, i got this by using the pythagorean theorem. a^2 + b^2 = c^2. in this case it would be 84^2 + b^2 = 85^2. then that would turn into 7056 + b^2 = 7225, subtract both sides by 7056 to get b^2 = 169, then square 169 to get 13 :)
Answer:
256, 3125/2, 64
Step-by-step explanation:
4^2(4^2)=16(16)=256
5^4(5)/2^1=625(5)/2=3125/2
(5+3)^2=8^2=8*8=64
Answer: r=6
Step-by-step explanation:
Because if 42 equals 7 times r you just have to divide 42 by 7.
