Answer:
n = 1
Step-by-step explanation:
First, rearrange the equation to standard form 0 = ax² + bx + c, when everything equals 0.
5n² = 5
5n² - 5 = 0
State the variables a, b and c.
a = 5; b = 0; c = -5
Substitute a, b, and c into the quadratic formula.

Substitute
Simplify inside the √ and bottom
Simplify the top
Final answer
Therefore the solution is n = 1.
The quadratic formula usually is written with x, but it can be solved with any variable in standard form.
Answer:
The vehicle would be going 60mph
24. (2x+2)+(2x+2)+(2x+2)=(x+8)+(x+8)+(x+8)+(x+8)
6x+6=4x+32
-6 -6
6x=4x+26
-4x -4x
2x/2=26/2
x=13
