Answer:
Step-by-step explanation:
If the new fraction is 8/12 I will show how to find it.
Let's say the original denominator is x, then the numerator is x-4, so we have (x-4)/x.
Then it says f we add 4 to both, so now we have x/(x+4) this equals 8/12. Now, keep in mind -4 cannot be an answer because it would make x/(x+4) be divided by 0 which wouldn't exist.
Now we just use algebra.
x/(x+4) = 8/12
12x = 8(x+4)
12x = 8x + 32
4x = 32
x = 8
So the original fraction (x-4)/x = (8-4)/8 = 4/8
Sorry it’s not that neat but I think the answer would be in the exact surd form root 233
Answer:
5000x^2 is the 4th term
Step-by-step explanation:
ok, 1 bionimial theorem coming right up
for a binomial expansion of (a+b)^n
the kth term is
means
n is 5
4th term
4-1=3
and a=2x
b=5
so
(10)(4x^2)(125)
5000x^2 is the 4th term
