  # New BB math trouble

<p>I already took all of the tests in the old blue book, and am now taking the first few new tests in the new BB. I was using the onlinemathlearning site to help me figure out how to solve the answers I was unable figure out, but now I only have the college board book owner's explanations to help me, and it's sooo much more complicated. Soo...I was wondering if someone can help me solve 12, 13, 14, and 16 on test #2 section 8? Thanks in advance :)</p>

<p>Argh, I meant to post this in just the SAT prep section. Hopefully that doesn't make too much of a difference...</p>

<p>post the question or a link it , i'll have a look</p>

<p>I hope my explanation helps and isn't too confusing.</p>

<h1>12 You can draw the rectangles so that they overlap. They don't only have to "fit" in the sample. So there is an infinite number of rectangles possible.</h1>

<h1>13. If 2^n + 2^n+1 = K, what does 2^n+2 equal in terms of K. First give n a value. I used n=1. 2^1 + 2^1+1 = 2 +4=6=K. 2^1 +2 = 2^3=8. Then I used the answer choices to find 4K/3 was the answer. I know there must be an easier way, but it only took me a minute to solve.</h1>

<h1>14 Because AB >AC, you know that angle z has to be larger than angle y. It doesn't matter which side BC or angle x is equal to.</h1>

<h1>16 When counting the squares on the edge of the game board, you will have 4 less boxes than 4 times the number of boxes on a side, due to the corners being on two sides.Take the answer choices and add 4. If the result is divisible by 4, that's the correct one. To make it easier to see, draw a 4x4 box and count the edge pieces.</h1>
