Answer:
0
Step-by-step explanation:
5*0=0
0^4=0
0^-3=0
If x +23 = 9, then, x = 9-23.
So x = -14
Multiply 18 * 3 and 20 * 3
18*3 = 54
20 * 3 = 60
Length = 54 cm ; Width = 60 cm
Area = L x W
54 * 60 = 3240
Area = 3240 cm
Recall your d = rt, distance = rate * time
thus

notice, the first car leaves at "x" time, the other leaves on hour later, or x + 1
the first car travels some distance "d", whatever that is, thus
the second car, picks up the slack, or the difference, they're 380 miles
apart, thus the difference is 380-d
