1. 16.64
a^2+b^2=c^2
pr^2=pq^2+qr^2
pr^2=14^2+ 9^2
pr^2=196+81
pr= sqr root of 277
16.64
2. 11.31
c^2-a^2=b^2
18^2- 14^2=b^2
b^2=324-196
b=sqr root of 126
b=11.31
hope it ! (btw im in connections academy to, good luck! )
the correct answer is b.
this is because an open circle means < or > & since the line goes left it is < -3.
the next one has a filled circle so it can only be ≥ or ≤ and since the line goes right from 1 it is ≥ 1
hope that
