Answer:

9

Explanation:

9 root 2 = root 81 x root 2 = root 162
Root 162 = 12.7279220614
9^2 + b^2 = 12.7279220614^2
81 + b^2 = 162
b^2 = 81
Root both
B = 9

What is the answer to this Question
mixer [17]
15. n - 6 = 21......add 6 to both sides
    n = 21 + 6
    n = 27

16. p + 1 3/4 = 4 5/8...turn mixed numbers to improper fractions
     p + 7/4 = 37/8....there is 2 ways to continue from here...I will show u            both

(1) p + 7/4 = 37/8....multiply everything by common denominator of 8, this gets rid of the fractions.
8p + 14 = 37 (result of multiplying by 8)
8p = 37 - 14
8p = 23
p = 23/8

(2) p + 7/4 = 37/8...subtract 7/4 from both sides
      p = 37/8 - 7/4...common denominator is 8
      p = 37/8 - 14/8
      p = 23/8

either way u use, u will arrive at the same answer
