That he is keeping track who he owes money to and when he has to do it
The surface area would be 16 square meters!
Let the integers be x and x + 2, provided x is even.
x(x + 2) = 360
x² + 2x = 360
x² + 2x - 360 = 0
(x - 18)(x + 20) = 0
x = 18, or x = -20
Thus, the integers are: 18 and 20, or -20 and -18
The absolute value equation which could be used to obtain the greatest and least possible temperature values when the temperature reading is 17°F is (17 ± 2)°F
- Thermometer accuracy = ±2°F
- Thermometer reading = 17°F
<u>The least possible value of </u><u>temperature</u><u> </u><u>can</u><u> </u><u>be</u><u> </u><u>calculated</u><u> </u><u>thus</u> :
- Thermometer reading - thermometer accuracy
<u>The highest possible </u><u>temperature</u><u> </u><u>can</u><u> </u><u>be</u><u> </u><u>calculated</u> thus :
- Themometer reading - thermometer accuracy
Hence, the absolute value equation which represents the scenario is (17 ± 2)°F

38 + 2n = 124
2n = 124 - 38
2n = 124 - 24 - 14
2n = 86
Therefore:
n = 43
