The answer id 12 meters.divide -2x^2+20x+48 by 2 to get x alone and then umbrella
2/5 of 50 is 20. 50-20=30. Making FG=30
The slope of the perpendicular line is -1/m.
it passes through the point (a,c) therefore:-
y - c = -1/m(x - a)
y = -1/m x + a/m + c answer
Parallel line:-
c = m(a) + b
b = c - ma
y = mx + c - ma Answer
