Answer: The answer is 288
Step-by-step explanation:
A cube has all sides the same length, check the picture below.
since the cube is just 6 squares stacked up to each other at the edges, we can simply get the area of each square and sum them up, and that's the surface area of the cube.
(3.5 · 3.5) + (3.5 · 3.5) + (3.5 · 3.5) + (3.5 · 3.5) + (3.5 · 3.5) + (3.5 · 3.5) .
Answer with Step-by-step explanation:
We are given that
Radius of circular disk=r=21 cm
dr=0.2 cm
a.Area of circular disk=A=



Where 

b.Relative error=
Relative error=
Percentage(%) error=
%
Plug in the second equation into the first equation for y.

Now put the variable on one side and constants on the other

Now plug that back into one of the original equations

So now you know

Its always a good idea to check
Answer:
16/(3(x+1))
Step-by-step explanation:
We can factor the denominator of the second term, which lets us see how to combine terms:
