Which Expression Is Equivalent To 20 3x 2A 3X 14B 3x 14 C 9x 21 D 17x 34 class=

Answer :

We have to simplify the expression:

[tex]20-3(x+2)[/tex]

and see which expression is equivalent.

We can do it like this:

[tex]\begin{gathered} 20-3(x+2) \\ 20-3\cdot x-3\cdot2 \\ 20-3x-6 \\ 20-6-3x \\ 14-3x \\ -3x+14 \end{gathered}[/tex]

This expression is equivalent to -3x+14.

Answer: -3x+14 [Option B]
