The answer is 12. The digit 2 is 2 times more than 1, so it matches the first part. 12 + 9 = 21. If you switch the digits of 12 around, you will get 21. So the answer is 12.
Answer:
The Answer is approximately: 20.22
Step-by-step explanation:
The distance formula is:
d = Sqrt ((x - x1)^2 + (y - y1)2)
The points are (5, -14), (-15, -17)
d = Sqrt ((5 - (-15))^2 + (-14 - (-17))^2)
d = Sqrt ((5 + 15)^2 + (-14 + 17)^2)
d = Sqrt (20^2 + 3^2)
d = Sqrt (400 + 9)
d = Sqrt (409) = 20.22

Answer:
30+(4x-4)=180-90(angle sum of triangle)
30+4x-4=90
4x+30-4=90
4x+26=90
4x=90-26
=54
x=54÷4
=13.5
