Then, we only to find the Xv of equation.
Xv = - b / 2a
Where,
a = 0.25
b = -30
Then ,
Xv = - (-30)/(2×0,25)
Xv = 30 / 0,5
Xv = 60
Hope this helps!
Answer:
n = -4
Step-by-step explanation:
1. the sum of 5 and some number translates to 5 + x.
2. 5 + x is getting multiplied by 4, so the equation will then become 4(5 + n).
3. This entire equation is equal to 4, which we can see where the problem says "is four". In other words, four times the sum of 5 + n is equal to 4. 4(5 + n) = 4
4. Now you can solve the equation. When solved, the answer is n = -4
