Simplify -3 p3 + 5 p + (-2 p2 ) + (-4) - 12 p + 5 - (-8 p3 ). Select the answer in descending powers of p . 1 - 7 p - 2 p2 + 5 p3 1 + 7 p + 2 p2 - 5 p3 5 p3 - 2 p2 - 7 p + 1 -5 p3 + 2 p2 + 7 p + 1

Step-by-step explanation:

Let's simplify step-by-step.

−3p3+5p−2p2−4−12p+5−−8p3

=−3p3+5p+−2p2+−4+−12p+5+8p3

Combine Like Terms:

=−3p3+5p+−2p2+−4+−12p+5+8p3

=(−3p3+8p3)+(−2p2)+(5p+−12p)+(−4+5)

=5p3+−2p2+−7p+1

=5p3−2p2−7p+1

the answer is b. 60. each interior angle in 120, so the exterior angle must be 60 in order to add up to 180
