18. 3(f+2) > 2f + 4\\3f + 6 > 2f + 4 \\3f-2f > 4-6\\f > -2\\ The answer is  I.

19. 4 < 6b -2 \leq 28\\4+2 < 6b \leq 28+2\\6 < 6b \leq 30\\6/6 < b \leq 30/6\\1 < b \leq 5

5. To get to the library from his house, Robert biked 6 kilometers due east and then
AURORKA [14]

Answer:

24 kilometers.

Step-by-step explanation:

The shortest path between two points is a straight segment that connects the two points.

Refer to the diagram attached. The 6-km segment and the 8-km segment are normal to each other. Together with the segment that joins the library and the house, the three segments now form a right triangle.

  • The two shorter segments are the two legs, and
  • The longer segment that joins the library and the house is the hypotenuse.

The length of the hypotenuse can be found with the Pythagorean Theorem.

\begin{aligned}\text{Hypotenuse} &= \sqrt{(\text{Leg 1})^{2} + (\text{Leg 2})^{2}}\\&= \sqrt{6^{2} + 8^{2}}\\&= \sqrt{36 + 64} \\&= \sqrt{100}\\&= \rm 10\;km\end{aligned}.

The length of the round-trip will equal to the sum of the length of the three segments: \rm 6\;km + 8\;km + 10\;km = 24\;km.
