What is
The GCF of 15 and 27 is give me a reason to or why it is that’s also

GCF-3

Step-by-step explanation: the factors of 15 are (1, 3, 15) and the factors of 27 are (1, 3, 27) ... which number(s) do you see that's in both ? 1 and 3, right ? as you can see, 3 is the greatest out of 1 and 3 ... so therefore the GCF is 3 .

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! )

#12 the answer is the third option
