Answer:
874.6
Step-by-step explanation
Profit = Sales - Costs
Profits by day:
Mon:
225 - (225*0.12) -9 = 189.0
Tue
260 - (260*0.12) -9 = 219.9
Wed
230 - (230*0.12)-9 = 193.4
Thu
180 - (180*0.12) - 9 = 149.4
Fri
150 - (150*0.12) -9 = 123.0
Total:
189+219.9+193.4+149.4+123 = 874.6
Answer:
P = 6x +4
Step-by-step explanation:
Use the given values in the formula for the perimeter of a rectangle:
P = 2(L +W)
__
You have ...
L = 2x +4
W = x -2
So, the perimeter is ...
P = 2((2x +4) +(x -2)) = 2(3x +2)
P = 6x +4
The perimeter of the rectangle is 6x+4.

now, we could check for the CA distance, however, we already know that AB ≠ BC, so there's no need.
