Thanks Vivian but no need to answer my questions anymore, I already took the GMAT.

Hi venkat Thank you and I wish you the best of luck as well! The Quant learning tool that I used from https://targettestprep.com/ was definitely helpful for my Quant, which was always my weak point. There is so much information on the site so it is impossible to get through it all in just 1 or 2 mon...

Thanks Rich, I definitely worked hard for it. I'm applying to B school now in round 2 applications. I'd prefer not to disclose more details about my score on the forum, but am happy to do so via private message.

Sincerely,

Melanie

@Brent@GMATPrepNow, yes that helps, thank you.

Thanks

Hi Brent,

Thank you, but I'm still not totally getting it. If you are factoring out 5^(x-3), then how did you get 5^(x-3)(5^3 - 1) . I.e., how does 5^x factored by 5^(x-3) become 5^3?

Also, how are you able to divide each side by 124 when it's only on right side of equation?

Thank you.

PS: Diagonal of a Rectangle / Area

A small rectangular park has a perimeter of 560 feet and a diagonal measurement of 200 feet. What is its area, in square feet?

a/ 19200
b/ 19600
c/ 20000
d/ 20400
e/ 20800

Correct answer: A

How do you solve this problem?

Great thanks
