Decide whether the statement is true or false. If false, provide a counterexample.
1. The equation 2x - 7 = 5 + x has exactly one solution TRUE
2. If x^2 = 16, then x must equal 8 or -8 TRUE
3. February 14 is Valentine's Day TRUE
4. If you visisted the Statue of Liberty, then you've been to New York TRUE
5. A point may lie on at most two lines FALSE A point may lie on more than zero to an infinite number of lines.

8. If m
The volume of a rectangular prism is represented by the following equation:
Where the variables are for volume, width, height, and length, respectively.
We are given that the area of one end is 16 cm² (units have to be correct when solving these problems, so it's 16 cm², not 16 cm as described in the problem). We know that 
Using this knowledge, we can change the volume equation to our needs.
Note: We know that A is 16 since it's given
The volume is 208 cm³ (once again, incorrect units given). Insert this into the equation.
Divide both sides of the equation by 16.
The length is 13 cm.
Let me know if you need any clarifications, thanks!
Jeb took 1/4 of 100 minutes(1 hour 40 minutes) =25 minutes for the first lap. . so the rest 75 minutes , Jeb took 1/3 time so 25 minutes for the second lap , the third lap Jeb took 100-50 = 50 minutes .
12 x 2 is 24 because its 12 doubled.
