Answer:
The answer is C
Step-by-step explanation:
If you're using a coordinate plane, I think it makes a trapezoid
6--3=9
15-6=9,
so
24+9=33,
33+9=42,
42+9=51
33,42,51
I got 16 but not 100% sure if it’s right
Sorry if it’s wrong, I tried my best
√8+√18−√32
√2^2·2+√3^2·2−√2^4·2
√2^ 2·√2+√3^2·√2−√2^4·√2
√2 is the answer
