Answer: x = ±√145
Step-by-step explanation:
√(17 + x) × √(17 - x) = 12
√(17 + x) (17 - x) = 12
Squaring both sides,
(√(17 + x) (17 - x))^2 = 12^2
(17 + x) (17 - x) = 144
17(17 - x) + x(17 - x) = 144
289 - 17x + 17x - x^2 = 144
x^2 = 289 - 144
x^2 = 145
x = ±√145
Answer:
6
Step-by-step explanation:
rise = 6
---------------------
run = 1
Rise is the y axis and run is the x axis. You look at the point and first go either up or down to the point you need to stop at. In this case we go down. Run is when you go sideways. Once you reach the line where the point lies, you need to go sideways 1 time to get to the point. Since rise is over run, 6 over 1
Therefore...........
6 over 1 = 6!!!!

Answer:
U.S has the least population density (29.115000021357) people per km²
Denmark has the greatest population density (124.723720797585) people per km²
Step-by-step explanation:
Formula:
=======================================
U.S population density : 272 648 000÷9 364 520 = 29.115000021357
Denmark population density : 5 248 000÷42 077 = 124.723720797585
Ghana population density : 18 339 000÷237 533 = 77.206114518825
Therefore:
U.S has the least population density (29.115000021357)
Denmark has the greatest population density (124.723720797585)
Answer:
188.60
Step-by-step explanation:
It is 188.60 since if you divide 754,40 by four you get 188.60
