Answer:
[tex]= -16p+4[/tex]
Step-by-step explanation:
First we simplify:
[tex]9-4(2p+3)-8p+7[/tex]
Then we distribute:
[tex]=9+(-4)(2p)+(-4)(3)+(-8p)+7\\=9+(-8p)+(-12)+(-8p)+7[/tex]
Lastly, combine like terms:
[tex]=9+-8p+-12+-8p+7\\=(-8p+-8p)+(9+-12+7)\\=-16p+4[/tex]
Hope this helps!
Have a good evening! :)
