Answer:
[tex]\boxed{\bold{15x+78}}[/tex]
Step By Step Explanation:
Apply Rule - (-a) = a
[tex]\bold{6\left(4x+12\right)-9x-18+4\cdot \:6}[/tex]
Multiply: 4 · 6 = 24
[tex]\bold{6\left(4x+12\right)-9x-18+24}[/tex]
Expand [tex]\bold{6\left(4x+12\right): \ 24x+72}[/tex]
= [tex]\bold{24x+72-9x-18+24}[/tex]
Simplify [tex]\bold{24x+72-9x-18+24}[/tex]
= [tex]\bold{15x+78}[/tex]
