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:
It's equivalent to the 3rd answer choice: y4 − 16y3 + 96y2 − 256y + 256

<span>The answer is D. Distributive
It is a distributive problem because you are are distributing the numbers within the parenthesis.
Hope this helped. Have a great day!</span>
Answer:
d=107
Step-by-step explanation:
7+5^2 *4
PEMDAS
Since there are no parentheses, we do exponents next
7+25*4
Then we multiply
7+100
Then we add
107
Answer: x = 10.3 ÷ 4
Step-by-step explanation: if we were to work this out forgetting about the equation it can be worked out by dividing the 10.3 by 4 to find the length of the pieces so, now to express it as an equation, we have to add x into our sum 4 × ? = 10.3 : 4x = 10.3. The answer for x would be x = 2.58.
