Well is just their sum, thus
Volume=Length * Width * Height
Volume= 8 * 4 * 2
Volume=64m
The slope for points (-9, 5) (-17, 5) is m = 0
3.2-3x+7
6-3x+7
-7 -7
-1= -3x divide both sides by -3
x=0.3
Y= 70° because the values in a triangle must equal 180 so,
60+50= 110
180-110= 70
and since x in this equation is the same as y, by default,
x= 70°
