SAT Prep questions blue book help?

<p>Hello, I'm a student and I was wondering if anyone could help me with any of these problems in the SAT blue book:</p>

<p>15 p. 427
11 p. 475
7 p. 489</p>

<p>Thank you for any help!!!</p>

<p>It would be helpful if you posted the actual questions.</p>

<p>15 since you know that pq is 6, and the graphs are symmetrical, so q(3,9) if you put 3 in the function y=x*x. then put q(3,9) into y=a-x^2, you’ll get a is 18
11, the third side should be as least as possible, thus it should be 30, then the perimeter is 30+30+50=110
7, you know thatx is 9, right?? then if y^z=16, z is bigger than y, think:16=2^4=4^2=16^1, so y is 2, and z is 4, xplus z is 13, choose D</p>

<p>hope you can post the questions here next time, otherwise i have to fetch my book and solve the problems for u.</p>
