A = 0.5 * 4 * (14 + 6)= 40 ft^2
The answer is: X = 1
3(x + 5) = 18
3x + 15 = 18
3x = 18 - 15
3x = 3
x = 3/3
x = 1
I hope this helps!!
Well the answer is 14 cm, because all you have to do is divide the length of LN in half
Draw a diagram to illustrate the problem as shown below.
Let v = speed of the westbound car, mph
Because the eastbound car travels 4 mph faster than the westbound car, its speed is (v+4) mph.
After 2 hours,
the westbound car travels 2v miles west, and the eastbound car travels 2(v+4) miles east.
Because they become separated by 208 miles, therefore
2v + 2(v+4) = 208
4v + 8 = 208
4v = 200
v = 50 mph
The westbound car travels at 50 mph.
The eastbound car travels at v+4 = 54 mph
Answer: The eastbound car travels at 54 mph.
