That would be 27+3y becuase if you see the 3 and 9 back to back that’s multiplication so 9x3 is 27 so you can put it as 27+3y and that’s how you do it so basically your answer is 27 hope that helped you!
Step-by-step explanation:
2*10+((4+10)x8)/2
=20+14*8/2
=76 sq meters
Area of a circle is:
A = pi(r^2)
A = 3.14(8^2)
A = 3.14(64)
A = 200.96
hope this helps :)
-3^-3=1/(-3^3)=-1/27 maybe a typo, because you don't have this as an option
could have been -3^-2=1/(-3^2)=1/9
-3^-1=1/(-3^1)=-1/3
-3^0=1
-3^1=-3
-3^2=9
