Tavon makes gift boxes of various sizes by removing a square from each corner
of a rectangular piece of cardboard and then folding up the sides, as shown in
the figure. He wants to know how much cardboard he uses for each box and the
volume of each box.
1. To make a box 3 inches deep, Tavon removes a
3-inch by 3-inch square from each corner of an
x-inch by x-inch square of cardboard. Write a
quadratic function A in standard form to model
the area of the remaining cardboard after the
corners are removed. Justify your answer.

"it's not the heat, it's the humidity".   that's a partly valid phrase you may have heard in the summer, but it's actually both.   the heat index, also known as the apparent temperature, is what the temperature feels like to the human body when relative humidity is combined with the air temperature.   this has important considerations for the human body's comfort.   when the body gets too hot, it begins to perspire or sweat to cool itself off.   if the perspiration is not able to evaporate, the body cannot regulate its temperature.   evaporation is a cooling process.   when perspiration is evaporated off the body, it effectively reduces the body's temperature.   when the atmospheric moisture content (i.e. relative humidity) is high, the rate of perspiration from the body decreases.   in other words, the human body feels warmer in humid conditions.   the opposite is true when the relative humidity decreases because the rate of perspiration increases.   the body actually feels cooler in arid conditions.   there is direct relationship between the air temperature and relative humidity and the heat index, meaning as the air temperature and relative humidity increase (decrease), the heat index increases (decreases).

step-by-step explanation:

there are 36 inches in a yard

25 : 36 = 0.69 yards (you can round to 0.70)
