Can you put a picture of the question so that i can help you out
So close! But instead of adding the multiplication sign after the number you need to add them before. Good job though! :)
Answer:
The answer is (C)
Step-by-step explanation:
because unit cube, more formally a cube of side 1, is a cube whose sides are 1 unit long .The volume of a 3-dimensional unit cube is 1 cubic unit, and its total surface area is 6 square units.
First find slope of line j
(-1-5)/(6+3) = -6/9 = -2/3
Perpendicular = opposite sign and reciprocal slope
Solution: 3/2
