Hey! Can you please help with blue book page 888 number 5? I looked in your blue book solution link but couldn't find one for this problem. Thank you.

Sure. You know from looking at the figure that 1) it’s a right triangle, and 2) it’s isosceles. There’s only one way that can happen, and that’s if it’s a 45-45-90 triangle. So aside from the two sides of length x you know about, you also know that the hypotenuse is x√2.

So you know the perimeter is x + x + x√2, and you also know that it’s 4 + 2√2. 

x + x + x√2 = 4 + 2√22x + x√2= 4 + 2√2x(2 + √2) = 2(2 + √2)x = 2

(You might not need to do all that algebra–many folks see the answer once they see the first step.)

Blue book Page 897, #30? Can you explain that? Thanks

The answer is A–the sentence should be left as is. 

B and C are both very long fragments–they have no main verb.

D is weird, tense-wise. The “having attended” makes it seem like she attended school first, and then earned a degree later, rather than the reality of having earned a degree as the culminating event in her attendance at Stanford.

E is a run-on.

Can you explain blue book page 910 #9? Like what is lines 8-14 saying? It's so confusing!!

A good shortcut for this question is to look at the context of the whole piece. Before “maps of perception,” you’re told that those maps of perception are what some of the most intense research in neuroscience today is focused on. Which of the answer choices in #9 sound like something that would be the subject of advanced neuroscience research?

bb page 914 #23 Can you explain what the author was trying to say when the young clerk thought he heard him say "I am your brother"?

Few and far between are the tearjerker moments on the SAT, but this is one. The new clerk, not yet accustomed to the way things are done in the office (i.e. everyone is cruel to poor Akaky for no good reason) hears in Akaky’s plaintive cries, “Leave me alone! Why do you insult me?” the words, “I am your brother.”

The young clerk’s heart goes out to Akaky, who is being bullied mercilessly. That’s what the author is saying when he says the clerk is “cut to the heart.”

P. 905 BB #10

Ah, the rare pure logic question in the SAT math section. You know that all men in the Williams family are over 6 feet tall. That doesn’t tell you anything about men who aren’t in the Williams family, so cross off choices B and C. It also doesn’t tell you anything about the women in the Williams family, so cross off D. E is a direct contradiction of the original premise, so you can cross that off, too. That leaves you with A. :)

Blue Book page 922 #12, please. Can you explain why A is wrong while D is right?

The fear is: “l fear for the seventeen-year-old songwriter looking forward to a career in the music business today.” If he or she is looking forward to a career, what evidence is there that he or she wouldn’t be devoted to it? The fear (and, really, the main idea of the whole passage) is that it’s not going to be easy to make money by writing music anymore.
