Answer:
to find slope you have to set the equation to y=
2x-4y=10
+4y +4y
2x=10+4y
-10 -10
2x-10=4y
/4 /4
1/2x-(10/4)=y
slope equals 1/2
Perpendicular lines have negative reciprocal slopes. All that means is " flip " the slope and change the sign.
slope = -2, or -2/1....so flip the slope...-1/2...and change the sign...1/2.
so the perpendicular slope would be 1/2.
Answer:
Volume: 8x1x12=96 inches^3
Surface area: 8x1x2=16
1x12x2=24
8x12x2=192
the total surface is: 16+24+192=232 inches^2
You need to add all of them up then devied by how many there are
