Answer:

$-2p^2-11p-35$

Step-by-step explanation:

$-2(p+4)^2-3+5p$

First we square the parenthesis. Apply FOIL method to multiply

$(p+4)^2= (p+4)(p+4)= p^2 + 4p+4p+16= p^2+8p+16$

$-2(p^2+8p+16) -3+5p$

distribute -2 inside the parenthesis

$-2p^2-16p-32-3+5p$

Now combine like terms

$-2p^2-11p-35$

What is the equation of the line that is perpendicular to y = one-fifth x + 4 and that passes through (5,–4)?

Brilliant_brown [7]

Answer:

y = -5x + 21

Step-by-step explanation:

perpendicular lines have slopes that are negative reciprocals.

The given line has a slope of 1/5, so the perpendicular line will have a slope of -5.

y = -5x + B

-4 = -5(5) + B

B = -4 + 25 = 21

y = -5x + 21
