<h3>The surface area of a piece of paper is
![13700\ mm^2](https://tex.z-dn.net/?f=13700%5C%20mm%5E2)
</h3>
<em><u>Solution:</u></em>
surface area of a piece of paper = 137 sq cm
<em><u>Use the fact that 10 mm = 1 cm to convert this area to mm^2</u></em>
![1\ cm = 10\ mm](https://tex.z-dn.net/?f=1%5C%20cm%20%3D%2010%5C%20mm)
Then,
![1\ cm^2 = 100\ mm^2](https://tex.z-dn.net/?f=1%5C%20cm%5E2%20%3D%20100%5C%20mm%5E2)
<em><u>Convert 137 sq cm to sq mm</u></em>
![137\ cm^2 = 137 \times 100\ mm^2\\\\137\ cm^2 = 13700\ mm^2](https://tex.z-dn.net/?f=137%5C%20cm%5E2%20%3D%20137%20%5Ctimes%20100%5C%20mm%5E2%5C%5C%5C%5C137%5C%20cm%5E2%20%3D%2013700%5C%20mm%5E2)
Thus, surface area of a piece of paper is ![13700\ mm^2](https://tex.z-dn.net/?f=13700%5C%20mm%5E2)
Answer:
x= -3, y=-6
Step-by-step explanation:
In the equation -5x-y=21, substitute y for 6+4x:
-5x- (6+4x) = 21
^^Solve for x.
X should come out to -3. To find y, plug -3 into either equation (-5x-y=21 or y=6+4x) and y should equal -6.

Answer:
16
Step-by-step explanation:
h(x) = 6 - x
h.h = (6 - x)²
h.h = x² - 12x + 36
h.h(10) = 10² - 12(10) + 36 = 16
