Add r to s, double the result, then multiply what you have by t

(rs2) x t

Step-by-step explanation:

r+s=rs

rsx2=rs2

(rs2)xt

2t(s+r)

Step-by-step explanation:

Add r to s

s+r

Double the result

2(s+r)

Multiply what you have by t

2t(s+r)

28

step-by-step explanation:

because that's the answer

for this case we have by definition, if two lines are perpendicular, then the product of their slopes is -1.

then, given the following line:

so,

we are looking for m_ {2}:

then, the line is given by:

we find "b" replacing the given point:

finally, the equation is:

option c
