<p>Would anyone mind helping me with a few math questions from the most current "Preparing for the ACT" from ACT's website? I missed and still don't really understand questions #44 and #55-59. Any help would be much appreciated, thank you.</p>

<li><p>H: There should be 8 lines of symmetry, if I’m not mistaken…you have to visualize carefully and make sure you don’t overcount lines.</p></li>
<li><p>C: Inequality in choice C holds iff x/3 > y/3, which holds iff x > y. This is true. The other choices need not be true.</p></li>
<li><p>J: [ABC] = xy sin 70, and [PQR] = xy sin 110. However sin 70 = sin 110, so the area of triangle PQR is also 30 cm^2.</p></li>
<li><p>E: Simple application of law of cosines.</p></li>
<li><p>G: Let a be the first term and d be the common difference. We have a + 5d = 8 and a + 9d = 13. Solving gives a = 7/4, d = 5/4. The sum of the first four terms is a + (a+d) + (a+2d) + (a+3d) = 4a + 6d = 4(7/4) + 6(5/4) = 29/2 = 14.5.</p></li>
<li><p>C: The polynomial must factor to (x+3)(x+3) (otherwise there would be a different value of x other than -3). Expanding gives x^2 + 6x + 9 = x^2 + mx + n, so m = 6.</p></li>
