Maybe something like this?
x^1/2 ( 1-x^2) = x^1/2 - x^5/2
Integrate 2/3 x^3/2 - 2/7 x^7/2 + C where C = a constant
5 parts + 2 parts = 7 parts total
5/7 are red 5/7 of 35 = 5/7 * 35 = 25 cans of red paint required.
1 inch = .51 mile
7 inches = 7 x .51 mile = 7*.51 = 3.57 (miles)

anyway, i have to go. BYE!
HOORAY!!! I HAVE 141!!
yes :) :D
each column has its own pattern, but each square has 2 choices so it is 2^5, or 32, and since 32 is less than 33, then by pigeonhole principle at least 2 rows have the same pattern.
HOPE THIS HELPED!
Your tied with last place to get onto the leaderboard now!
It worked! I'll make an account soon
\(ext{coding practice please make a new line after this}\\6+8=14\)
i am close to getting on leaderboard :)
:P lololol
Yeah, I saw
oh thanx :P i answered a lot
I saw you go from 40 points to 100 in one day. Great job
hello wow i am lonely
cool!
1. add 13 to both sides => 5|x-3|=80
2. divide by 5 on both sides => |x-3|=16
3. 2 cases:
x-3 is positive => x-3=16, x = 19.
x-3 is negative => x-3=-16, x = -13.
THANK YOU!!!!!!!!

i think its a, b, c, d.
Take the sqrt of both sides to get
v+6 = + or - 18
v = -24 , 12
Solve for x: abs(x - 3) = 16
Split the equation into two possible cases: x - 3 = 16 or x - 3 = -16
Add 3 to both sides: x = 19 or x - 3 = -16
Add 3 to both sides: x = 19 or x = -13
120 I
I'm pretty sure....
The question isn't really clear....
