Explain why
constant terms expressed as different rational
number types can be combined.

Following are the solution to the given question:

Constants, as the name implies, remain constant, which means that their value never changes.For example, 2 is always 2 and 9.4 is always 9.4, and variable values, on the other hand, can vary. Considering the variable 2x as an example.When and when , hence the value of varies depending on what is.We can't combine constants and variables and they're not the same item; one can change while another can't, and you can't join terms that are not the same.

step-by-step explanation:

always plug in x. in this case, x equals 4.

i'm going to first solve 4(2+3x)

1) 4(2+3(4)) use pemdas to solve.

i'm going to multiply whats in the parenthesis first, so 3 times 4=12.

2)4 (2+12) i'm then going to multiply 4 by both numbers in the parenthesis (because multiplying comes before adding)

4 times 2= 8.   4 times 12= 48

4) (8+48)= 56 (answer)

i'm then going to solve 8+12x and plug in 4 for x.

1) 8 +12(4)

multiplying comes before adding, so i'm gonna multiply 12 and 4.

12 times 4= 48.

2) 8+48=56

both equal the same!

X=y+4 is the answe
