From a board 8 feet in length, emmet cut two ,2 and 1 over3-foot bookshelves. how much of the board remained?

  5

Step-by-step explanation:

To get how much of the board remained, we simply subtract the length Emmet cut from the initial length of the board

Initial length of the board = 8

Length cut out  =    2

                         =

Length of board remained = Initial length of board - Length cut out

                                            = 8 -

                                             =

                                             =

                                          = 5

Therefore the length of the board remained  is 5 feet

hello from mrbilldoesmath!

answer:

the domain is the set { -2, 0, 2, 3}

discussion:

the domain is the set of x values in the ordered pairs (x,y). taking the x, or first component, of each ordered pair gives   -2, 0, 2, 3.
