It would be...
(18 +28) divided by two
then take that and multiply it by the height - 5
the 6 in this equation doesn't matter because it is not the height of the shape
The value of given expression when m = 3 is 27
<h3><u>Solution:</u></h3>
Given expression is 
We have to evaluate the given expression for m = 3
To find for m is equal to 3, substitute m = 3 in given expression
From given expression,

Plug in m = 3 in above expression
------ eqn 1
We know that,
can be expanded as,

Applying this in eqn 1, we get

Simplify the above expression

Therefore, for m = 3 we get,

Thus value of given expression when m = 3 is found
3/4 is 0.75.
3/4 is larger than 0.7
5x + 20
5(x) + 5(4)
5(x + 4)
4250 millimeters.
Half of 8.5m is 4.25m.
4.25 m to mm is 4250.
