If it's just simplifying the equation then the answer is:
-4.338
Answer:
About 4.2 ft
Explanation:
The area of the traingle can be calculated in two ways.

where width = 4.4 ft and length = 13.6 ft.
Putting in the values for width and length gives

The other way that the area can be calculated is

where height = vertical length and base = 14.3 ft; therefore.

This must equal the area of the triangle we found above; therefore,


dividing both sides by 7.15 gives


which is our answer!
Um 3+u so i think 5 im pretty sure im in 2 grade btw
Trains depart after every 4 minutes.
Total time train takes to complete a circuit= 24 minutes
Evan sets off at 8:30 am, so he will be back at 8:54 am.
So time of trains coming in opposite direction:
8: 34 am
8:38 am
8:42 am
8:46 am
and 8:50 am
5 trains coming in opposite directions.
Now the trains started at 8:06 am from the stations are:
8:06 am
8:10 am
8:14 am
8:18 am
8:22 am
and 8:26 am.
So there are 6 trains started the circuit at 8:06 am.
Now total number of trains=6+5=11 trains
Answer: 11 trains will pass on complete circuit.
