Answer:
Step-by-step explanation:
What you do is try to find l by using the given information.
We can start by saying that
A=L*W
Now it's easy algebra
Divide both sides by W
L=A/W
Area and length are given .
A=((m^3-3m+2)/2m^2-7m+3)/(m^3+m-2)/(2m^3+3m-2)
Try to work it out if you can't then tell me in the comments we'll figure it out.

This happens whenever

or

. More generally,

whenever you start with one of these angles and add any multiple of

, so the general solution would be

, where

is any integer. (Notice that when

, you end up with

.)

Answer:
m= -16
Step-by-step explanation:
m/4+3= -1
-3 -3
m/4= -4
*4 *4
m= -16
Wouldn't it be 80 degrees since the milk was supposed to cool it down you would have to subtract 50 from 150 and 10 from 90
