slope = y1-y2   /   x1-x2

    = 6- -2  /   -2-  -4

    =8 / 2  =4

y=mx+b form

y = 4x + b      Sub in one of the points to find b

6 = 4(-2) + b

b = 14

y = 4x+14      when x = 0     b is the y intercept = 14

you just copied CPhill's answer!!!

here is the decimal \(0.9 \overline{7}\)

This is written as \(9\frac{7}{9} \cdot \frac{1}{10}\)

which equals to \(\frac{44}{45}\)

as the question asks

\(44-45={\boxed{-1}}\)

niceeee.

here's a way

\(240=2^4\cdot3\cdot5=2^3(2\cdot3\cdot5)\). For \(240k\) to be a perfect cube (and not a perfect square), \(k\) must be at least \(2^2\cdot3^2\cdot5^2=\boxed{900}\).

240x60=14400, which is not a perfect cube

. 

i dont think they want to cheat by searching it up...

x² + 15x + 54 factors to (x + 6)(x + 9)      a = 6 and b = 9   

x² – 17x + 72 factors to (x – 9)(x – 8)                      b = 9 and c = 8   

so a + b + c  =  6 + 9 + 8  =  23   

EP the smart's answer

Sum of convex decagon interior angles = 1440                 ( that is (10-2  * 180)   )

(5 *2 + 8*2 + 9*6) y = 1440

80y = 1440     solve for y

Prime factorization:

sqrt (x^4  *    3 * 2 * 2 * 5    *  3 * 2 * 2 *     3*3*7    *    7*2*3 ) =

x^2 * 2^2 * 3^2 * 7 sqrt ( 5*2*3)   

just keep simplifying

what is the distance between each wall?
