Answer
d. 5x - 10
Step-by-step explanation
Substituting x = 6 into the first expression:
[tex]\begin{gathered} 2x+10= \\ =2\cdot6+10= \\ =12+10= \\ =22 \end{gathered}[/tex]Substituting x = 6 into the second expression:
[tex]\begin{gathered} 3x+3= \\ =3\cdot6+3= \\ =18+3= \\ =21 \end{gathered}[/tex]Substituting x = 6 into the third expression:
[tex]\begin{gathered} 4x-2= \\ =4\cdot6-2= \\ =24-2= \\ =22 \end{gathered}[/tex]Substituting x = 6 into the fourth expression:
[tex]\begin{gathered} 5x-10= \\ =5\cdot6-10= \\ =30-10= \\ =20 \end{gathered}[/tex]
