Answer:
2376 square feet
Step-by-step explanation:
40 x 15 = 600
40 x 24 = 960
1/2 x (24 x 9) = 108
600 + 600 + 960 + 108 + 108 = 2376
So the distance formula is
. Using this, our equation is
and we can solve for it as such:

As we see with this radical, the sum that's under it is 15^2 + 8^2, or the third option.
Answer:
perpendicular
Step-by-step explanation:
2-x =3y
3y = 2-x
y = -1/3x+2/3
slope is -1/3
2y +10 = 6x
2y = 6x -10
y = 3 -5
slope is 3
-1/3 and 3 are negative reciprocals so the lines are perpendicular.
142
1•4= 4
5•5= 25
1•11= 11
6•18= 102
102+11+25+4= 142
