<h3>Answer: 722.5792 square centimeters</h3>

Work Shown:

$112 \text{ in}^2 = 112 \text{ in}^2 \times \frac{2.54 \text{ cm}}{1 \text{ in}} \times \frac{2.54 \text{ cm}}{1 \text{ in}}\\\\112 \text{ in}^2 = (112 \times 2.54 \times 2.54) \text{ cm}^2\\\\112 \text{ in}^2 = 112 \times (2.54)^2 \text{ cm}^2\\\\112 \text{ in}^2 = 722.5792 \text{ cm}^2\\\\$

Notes:

1 inch = 2.54 cm exactly
The conversion factor $\frac{2.54 \text{ cm}}{1 \text{ in}}$ is used to convert from inches to cm. The inches unit in the denominator cancels with one of the inches unit from the original 112 square inches figure.
We use two identical copies of the same conversion factor to convert from square inches to square centimeters. This is the "multple conversion" your teacher is referring to.
Think of "square inches", aka $\text{in}^2$ , as "inches times inches". Or think of a 1 inch by 1 inch square that has an area of 1 square inch. The same applies for the square centimeter unit as well.

In at least five (5) sentences, explain the effects of changing the “m" and the "b" in y=mx+b.

victus00 [196]

Changing the “m” or “b” would change the overall line on the graph. Meaning the line could be steeper or flatter. It could also change whether the line has a positive slope or negative. Likewise, when you use negative numbers for the m, the line will have a negative slope and will have a decreasing look to it. When you use negative numbers for the b, the y-intercept will be negative which will put the line further down the y-axis.

I hope this is what you were looking for! I kinda did it off the top of my head so of course feel free to change anything!!
