X times S = $27. X is the cost of the large sacks and S is the amount of sacks. Once they are multiplied it should equal $27. If this is incorrect please let me know so I can try and correct mistakes made.
<span>(x - 8) (x + 8)
= x^2 - 8x + 8x -64
= x^2 - 64</span>
When rounding to the hundredth, you must look at the thousandths place. In this case the thousandths place is less than 5 so it rounds down to 0, making the rounding .17
15 = 1*15 = 3*5
36= 1*36 = 2*18 = 3*12 = 4*9 = 6*6
Because only two whole number factor pairs make up 15, there are only two possible rectangles with whole number side lengths.
Because only five whole number factor pairs make up 36, there are only five possible rectangles with whole number side lengths.
