Answer:
A 20 sqrt(2)
Step-by-step explanation:
4 sqrt(50) + 4 sqrt(12) - 2 sqrt(27) minus 2 sqrt(3)
We know that sqrt(a) sqrt(b) = sqrt(ab)
this is the first expression
4 sqrt(25)sqrt(2) + 4 sqrt(4)sqrt(3) - 2 sqrt(9)sqrt(3)
4*5sqrt(2) + 4*2 sqrt(3) - 2*3 sqrt(3)
20 sqrt(2) +8 sqrt(3)-6sqrt(3)
20 sqrt(2) +2 sqrt(3)
Now we subtract 2 sqrt(3) from the above expression
20 sqrt(2) +2 sqrt(3) - 2 sqrt(3)
20 sqrt(2)
The probabilty is 6/26. i thnk im not really good with this stuff

Answer:
The speed of the jet in still air is 415 mph and the speed of the wind is 19 mph
Step-by-step explanation:
we know that
The speed is equal to divide the distance by the time
Let
x -----> the speed of the wind in miles per hour
y ----> the speed of the jet in still air in miles per hour
we know that
<em>With a tailwind</em>

----> equation A
<em>With a headwind</em>

----> equation B
solve the system of equations A and B by elimination
Adds equation A and equation B

<em>Find the value of x</em>



therefore
The speed of the jet in still air is 415 mph and the speed of the wind is 19 mph
