Answer:
40/21
Step-by-step explanation:
-4/7+(-4/3)
common factor is 21
=21/7×-4-21/3×4
=3×-4-7×4 all divided by 21

=40/21
Okay! So to start this problem, we need to look at the given information a little closer to make sure we have everything we need! This is a triangular pyramid, meaning that it has a total of 4 sides, which are all congruent triangles, meaning they all have the same surface area! We are also given the total surface area, which is 2304 cm^2.
If we need to find out how big one of the sides are, we should just have to divide the total surface area by 4, because there are 4 sides with the same surface area! 2304/4 = 576 cm^2, so your answer should be A) 576 cm2!
