Answer:
[tex]182[/tex]
Step-by-step explanation:
First we expand this equation using the rule
[tex]x(y + z) = xy + xz[/tex]
Thus,
[tex]12 - 2 + 4(1 + 42)[/tex]
[tex]12 - 2 + 4 \times 1 + 4 \times 42[/tex]
[tex]12 - 2 + 4 + 168[/tex]
Add/Subtract from left to right:
[tex]10 + 4 + 168[/tex]
[tex]14 + 168[/tex]
[tex]182[/tex]
