Important: Use the symbol "^" to denote exponentiation:
<span>x3 – 9x2 + 5x – 45 NO
</span><span>x^3 – 9x^2 + 5x – 45 YES
Look at the first 2 terms. They can be rewritten as x^2(x-9). Then look at the last 2 terms. They can be rewritten as 5(x-9). So, x-9 is the common factor here. Thus, the original expression becomes:
(x^2-5)(x-9).
Note that x^2-5 can be factored, so that the final 3 factors are:
(x-sqrt(5)), (x+sqrt(5)), (x-9).</span>

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:
3 over 2
Step-by-step explanation:
<u>Simplify:</u>
- 3⁻⁴*2³*3²/2⁴*3⁻³ =
- 3⁻⁴⁺²⁻⁽⁻³⁾*2³⁻⁴ =
- 3⁻²⁺³*2⁻¹ =
- 3/2
<u>Correct answer choice:</u> the first one 3 over 2
