In XY plane point P has coordinates (a,b) and point Q has coordinates (c,d)
What is the distance between P and Q?
1) b-d = 4
2) a-c = 3
I know this is easy but I can't wrap my mind around how it is C. If anyone can give me a quick explanation thanks.
Also, What is the greatest prime factor of (4 to the 17th) - (2 to the 28th). I guessed 7 but I am terrible with exponents and don't know how I got it.
Take the test Saturday and currently testing around 670 but would like to break 700. My biggest mistakes come in sentence correction and Data sufficiency and I always make a couple stupid mistakes.
I am trying to counteract this by going over manhatten SC book before saturday, and working some magic on Data sufficiency. I always finish both sections with about 5-10 minutes left so I think I just need to take some time and double check. Sometimes I finish the qualitative section with 15-20 minutes left.
That's my short story, and thanks for the help on these two problems.
