The expression equivalent to 16a + 24b is 8(2a + 3b).
In order to determine which expression is equivalent, the expression has to be simplified. To do this, divide the two terms, by factors of both terms.
The factors of a number are numbers that divide the original number evenly.
Factors of 16 and 24 = 1, 2, 4, 6, 8
The expressions could be:
2(8a + 12b)
4(4a + 6b)

Answer:
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
