Answer: x=4
Steps: (I am assuming your question has a typo in it and by "c" you meant "x")
The rational expression equals zero

only when the numerator equals 0 (the denominator cannot ever be zero):

and that happens only for x=4

Answer:
15x + 15
Step-by-step explanation:
Combine like terms. Like terms are terms with the same amount of variables. Set the equation so that the terms are grouped:
6x + 9x + 6 + 9
Combine like terms:
(6x + 9x) = 15x
(6 + 9) = 15
15x + 15 is your answer.

We know, S.I. = P * R * T / 100
Here, S.I. = 125
P = 750
r = 6.25
Substitute into the formula:
125 = 750*6.25*t / 100
4687.5 * t = 12500
t = 12500 / 4687.5
t = 2.67
t = 2 2/3
In short, Your Answer would be 8/3 Years
Hope this helps!
