Answer: To determine whether 2.5 is a solution to the equation 4n + 4 = 14, we can substitute 2.5 for n in the equation and see if it makes the equation true.
So, if we substitute 2.5 for n in the equation:
4(2.5) + 4 = 14
Expanding the left-side expression:
10 + 4 = 14
Simplifying further:
14 = 14
Since the equation is true, we can conclude that 2.5 is a solution to the equation 4n + 4 = 14.
