Quick! i can't figure it out!
+6p - 3q + z - 3p + 2q - z - p + 00q

look below

Step-by-step explanation:

lets do this!!

find the common variables cuz if variables are different they can't add so

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! )
