Answer:
60
Step-by-step explanation:
straight lines are 180
since all lines are parallel
180 - 120 = 60
-2x^2 + 500x - 350
You need to plug in the equations for C(x) and R(x) into the equation P(x)= R(x) - C(x) and solve.
I think you have to combine like terms to solve this one. (6d - 3d) + (5 - 2) = 3d + 3
If the chalkboard is just rectangular we can just use:
(2 x L) + (2 x W)
or
L+L+W+W
L= Length
W= Width
First align the decimal points and the numbers, then add the extra 0's if needed. Lastly, add and the total answer is 14.225.
