Adding Polynomial Expressions.
Simplify

#1

(-r^2+8pr-p)+(-12r^2-2pr)+(8p+3r^ 2)

#2

(rs^2-s-6)+(2rs^2-3s+1)+(s+4rs^2)

the answer is (-8,-5)

step-by-step explanation:

the endpoint to midpoint is half the length. the length is (-2,-1) so when you are at the midpoint just add it to it to find your answer -6+(-2)= -8 and -4+(-1)=-5 so (-8,-5)

a is 8.b is 10.c is 10.5. d is -.5

step-by-step explanation:

just minus the smallest number from the biggest.
