It's 7:10. There are 14 gray and 20 black, which simplifies to 7:10.
a2+b2=c2
a=x
b=24
c=26
a2+24 squared=26 squared
a2+576=676
-576 -576
a2=100
Then, square root both sides.
It should be a/x=10
= -30a^5b + 12a^4b^3 + 6a^3b^2 + 10a^3b^2 - 4a^2b^4 - 2ab^3
= -30a^5b + 12a^4b^3 + 16a^3b^2 - 4a^2b^4 - 2ab^3
answer
B. -30a^5b + 12a^4b^3 + 16a^3b^2 - 4a^2b^4 - 2ab^3
Idek sorry have a nice day
