Answer:
C
Step-by-step explanation:
The surface are of the prism will be the area of a each side added together. The work would look like this:
SA = 2[(l×h)+(l×b)+(b×h)]
SA = 2(lh+lb+bh)
But if you multiply each dimension by 5, the area becomes
SA = 2[(5l×5h)+(5l×5b)+(5b×5h)]
SA = 2(5²lh+5²lb+5²bh)
SA = 5²×2(lh+lb+bh)
SA = 5²area
Since 5² = 25, then the the surface area is multiplied in size by 25.
14.50x > 85
divide both sides by 14.5
x>85/14.5 = 5.86 hours
x has to be greater than 5.86 hours
what is the question then
9
18 x 1/2
18/2
