Is this
Step-by-step explanation:
U= {A,B,C,D,E,F,G}
X = {A, B, C, D}
Y = {A, C, E, F}
a) X or Y = {A, B, C, D} and {A, C, E, F} = {A, B, C, D, E, F}
B) X and Y = {A, B, C, D} or {A, C, E, F} = {A, C}
c) Complement of X = {A,B,C,D,E,F,G} - {A, B, C, D} = {B,D,G}

g^3 - 7
write
(2g^2+3g-8)-(5g+1)
(5g^3-8)-(5g+1)
and then you get g^3 - 7
sorry if it is not write but it should be
