Answer:

$-p^2+32$

Step-by-step explanation:

Start by expanding the $-2$ into the $(p-4)$ bracket using the distributive method:

$-2(p-4)\\-2p + 8$

Now, expand the result into the remaining bracket:

$(-2p + 8)(p+4)\\-2p^2 -8p+8p+32\\-2p^2 + 32$

40 = x% of 32

32x = 40
x = 40/32
x = 1.25

multiply by 100 to convert to percentage...

x = 125%

40 is 125% of 32
