19.2
To find the hypotenuse the equation would be: a^2 + b^2 = c^2.
12 squared is 144 and 15 squared is 225. Add them and you get 369. Then, square root 369 to isolate c. It'd be about 19.2
Answer:
y=30
Step-by-step explanation:
f(-2)=18+3(-2)^2
f(-2)=18+3*4
f(-2)=18+12
f(-2)=30
12+40+28+12= 92
40-12= 28
92+28= 120
28-12= 16
120+16= 136
P=136
There are 3 holes because if you do 4 thats to high cuz you would get 12 hope this is what you mean
