Pleas on 10-14 and if you can check 9 that would be great

9) n=7
10) y=66
11) w=9
12)g=42
13)f= -15
14) p=2

9. n = 7 because 5 × 7 = 35, and 35 + 8 = 43
11. w = 9 because 8 × 9 = 72, and 72 - 15 = 57
I don't know what 12, 13 and 14 is, sorry.

The distance from point a to point c across the coordinate plane is aproxamatly 8.94 rounded to the nearest hundredth. you use a^2 + b^2 =c^2
