Answer:
43 stitches.
Step-by-step explanation:
We have been given that each pant's leg has an opening with a circumference of 8.5 inches. It took 15 stitches to make 3 inches in width. We are asked to find the number of stitches required to make up the circumference.
Let us find stitches needed to make 1 inch by dividing 15 by 3.
Since 5 stitches make 1 inch, so to find stitches needed to make 8.5 inches, we will multiply 8.5 by 5 as:
Upon rounding to nearest stitch, we will get:
Therefore, 43 stitches will make up the circumference.
Surface area is 34 units2 or sq.
the volume is 10 units3 or cubed.
volume is the amount of cubes on the inside, and the surface area is each surface added together

yes wait im doing it. do I put them un order
Descartes' rule of signs tells you the one sign change in the coefficients means there's one positive real root. If you change the sign of the odd-power terms, the signs become -++-, so have two sign changes. This means there are 0 or 2 negative real roots.
A graph shows there to be 3 real roots, two of which are negative. Thus there are no complex roots.
If the area is 120, each length is root(120)
root(120) = 2*root(30)
so the perimeter is:
4 * 2 * root(30) = 8 root(30)
which is approximately 43.8
