Answer:
The width of the frame is 0.0746 meters
Step-by-step explanation:
We are told that after the frame has been attached to the solar collector, the area that is left exposed is
. As we see in the figure, the dimensions of this area are
and 
where
is the width of the frame.
The product of these dimensions must equal the exposed area:

Now since
and
we have:

we expand this and solve for x using the quadratic formula:


we get two solutions:


We take the second solution i.e
, because first one gives a width larger than the dimensions of the solar collector which cannot be possible.
Thus the width of the frame is 0.0746 meters.
Answer:
Standard form:: Ax + By=C
Step-by-step explanation:
Simple...
change them all into decimals...or fractions..or percents:
52%, 0.57,

--->>
52%--->>0.52
0.57--->>0.57

-->>0.4
Now you can order from least to greatest....

, 52%, 0.57
Thus, your answer.
