What is 1/2 x (6 x 4)+3 + 2 show your work

Determine whether the set of whole numbers is closed under addition. explain why the set is or is not closed. give an example.

Consider this equation. |y + 6| = 2 what can be concluded of the equation? check all that apply. there will be one solution. there will be two solutions. the solution to –(y + 6) = 2 will be also be a solution to the given absolute value equation. the solution(s) will be the number(s) on the number line 2 units away from –6. the value of y must be positive since the variable is inside absolute value signs.
