Answer:
Add up the area of all the sides
Step-by-step explanation:
Surface area is the shell of a 3d shape, not the volume so you add the outside of the shape.
Hope this helps! :)
Answer:
2x - 3y
Step-by-step explanation:
-1/4(-8x+12y) = 2x - 3y
2t = 40 - 2w
t = 40/2 (-2/2)w
t = 20 - w -- rearrange
t = -w + 20
t + w = 15
t = -w + 15
same slope, different y intercepts.....parallel lines, no solutions
Answer:
p = -2
Step-by-step explanation:
px + 2y + 8 = 0
px + 2y = -8
p(4) = -8
p = -2
It will be 24.4
I hope this helps
