First you have to solve for x. X=32.
5*32-12=148
148=(3y-8).
y=52
Step-by-step explanation:
surface area of cylinder is
2×pi×r (h+r)
2×22/7×2 (4+2)
88/7 (4+2)
75.4 cm square
8 because 12-4=8. Im writing this part for the 20 characters
PEMDAS
yo might be tricked to do 2(-7) but that's multiplcation
so expoments
(-6)^2=36
now we have
36/12-2(-7)
mulitipictioan or division whicever comes first
division
36/12=3
multiplcation 2(-7)=-14
now we have
3-(-14)
3+14
17
answer is 17
