Answer:
the last one
Step-by-step explanation:
5(x+4)=-15
Distribute
5x+20=-15
Subtract 20 from both sides
5x=-35
Divide both sides by 5
x=-7
Final answer: The number is -7
Answer:
2x + 3y +1
Step-by-step explanation:
-2x + 4x -6y + 9y +3 -2 (arranging)
2x + 3y + 1
Answer:
the first one
Step-by-step explanation:
the 4x's cancel out and 8 does not equal -14 so...
The impulse that was produced by this aircraft jet engine is 5,400 Ns.
<u>Given the following data:</u>
To determine the impulse that was produced by this aircraft jet engine:
<h3>How to calculate
impulse.</h3>
Mathematically, impulse is given by this formula:

<u>Where:</u>
- F is the force or thrust.
- t is the time measured in seconds.
Substituting the given parameters into the formula, we have;

Impulse, I = 5,400 Ns.
