-31p + 16

Step-by-step explanation:

-8(4 p -1) - 7p+8( p+1)​

-8(4p) -8(-1) - 7p +8(p) +8(+1)

Simplify:

-32p + 8 - 7p + 8p + 8

Note: the multiplication of opposite sign gives negative number. While multiplication of same sign gives positive number

Collect like terms:

= -32p - 7p + 8p + 8 + 8

= -31p + 16
