if you don't know the answer don't answer​

Answer 1

Step-by-step explanation:

p = -2

4p+7

= 4(-2) + 7

= -8+7

= -1

-3p^2+4p+7

= -3(-2)^2 + 4(-2) +7

= -3(2) - 12 + 7

= -6 -12 + 7

= -11

-2p^3-3p^2+4p+7

= -2(-2)^3 - 3(-2)^2 + 4(-2) + 7

= -2(-8) - 3(2) -8 + 7

= 16 - 6 - 8 + 7

= 9

when there's an even power on negative number it converts it to positive ...
