The max area is always a square:

P = 200, s = 200/4 = 50, A = 50*50 = 2500 square meters.

For this problem, we have to divide 1000 km by the product of hours per day and average speed:

$days=\frac{1000}{10*8=80}$

$days=\frac{960+40}{80}$

$days=\frac{960}{80}+\frac{40}{80}$

$days=12+\frac{1}{2}$

$days = 12.5$

Stewart will take 12.5 days to travel 1000km.

$\frac{27}{64}=0.421875$

$\frac{27}{32}=0.84375$

Right.

Use the keyboard

$8*8=64=8^2$

Right?

Good job.

I'm assuming you mean simplify? I'm gonna do that.

$-6t*4m*(-m)$

-m can be expressed as -1*m, and -6t can be expressed as -1*6t: $-1*-1*6t*4m*m$

-1 * -1 = 1: $1*6t*4m*m=6t*4m*m$

m * m = m²: $6t*4m*m=6t*4*(m*m)=6t*4*m^2$

Factor out 2: $2(3t*2m^2)$

The simplest form of the expression is $(2(3t*2m^2))...or...(6t*4m^2)$

I don't understand that behemoth of a solution because I was too lazy to read it, but you got the right answer, except there is a much, MUCH simpler solution.

A US cup is approx. 0.24, so 1L/0.24 = 4.1666667, you have enough. Actually, you have a smidget more than enough.
