We have the following equation:
 s = ut + 1 / 2at ^ 2
 Clear a for the equation:
 1 / 2at ^ 2 = s-ut
 at ^ 2 = 2s-2ut
 a = 2s / t ^ 2-2ut / t ^ 2
 Rewriting:
 a = (2s-2ut) / (t ^ 2)
 Answer:
 
An equation that represents a in terms of other variables is:
 
C. 2s-2ut / t ^ 2

What is the surface area of this right prism?
Amiraneli [1.4K]

Answer:

Since the 'base' and 'top' of any prism have the same shape, the surface area can be found by

surface area of prism = 2 * area of base + perimeter of base * H

So for the rectangular prism in your example..

surface area = 2LW + 2(L+W)H

= 2 * 7 * 4 + 2*(7+4)*5

= 56 + 2 * 11 * 5

= 56 +110

= 166 sq cm

Hope this helps
