I don't understand your question, expressions do not end with equal signs. Or are you just asking how to write the expression?
2*((3*x)^3)+2(y^2) then simply replace the x with "-2" and y with "sqrt(12)"
2*(-2)^3+2(12)
-16+24
8

Answer:
The Answer is 3 - sqrt7
Step-by-step explanation:
2/3 + sqrt7 the starting equation
You multiply it by the conjugate which is 3 - sqrt7
= 2(3 - sqrt7) / (3 + sqrt7) (3 - sqrt7) the equation after you multiply by 3 - sqrt7
(3 + sqrt7) (3 - sqrt7) = 2
= 2(3 - sqrt7) / 2 the equation after you simplify (3 + sqrt7) (3 - sqrt7)
Divide out the 2's
= 3 - sqrt7/1 the equation after you divide out the 2's
= 3 - sqrt7 is THE ANSWER
The answer to this is y=88 degrees
