<span>[ (1 / 36) - (1 / x²) ] / [ (1 / 6) + (1 / x) ]
[ (x² - 36) / 36x² ] / [ (x + 6) / 6x ]
</span>remember that<span>:
x² - 36 = (x + 6)(x - 6)
so
[ (x+6)(x-6) / 36x² ] / [ (x + 6) / 6x ]
[ (x+6)(x-6) / 36x² ] * [ 6x / (x + 6) ]
6x / 36x² = 1 / 6x
[ (x+6)(x-6) / 6x ] * [ 1 / (x+6) ] -------------------- > </span>(x - 6) / 6x<span>
The answer is </span>(x - 6) / 6x<span>

Answer:
25.1!
Step-by-step explanation:
all you have to do is C=2πr=2·π·4≈25.13274
To calculate the circumference of a circle, multiply the diameter of the circle with π (pi). The circumference can also be calculated by multiplying 2×radius with pi (π=3.14).
Hope that helped! :)
Step-by-step explanation:
Using the given formula :
I = P × R × T
I = 80000 × 15/100 × 4
I = $48000
He saves = 48000 +80000 = $128000
Answer:
83% remains in the box
Step-by-step explanation:
Here, we are interested in calculating the percentage of donuts remaining in the box.
From the question, we are told that 2 was eaten, the number of donuts left = 12-2 = 10 donuts
The percentage of donuts left would be;
Number of donuts left/Total no of donuts * 100%
= 10/12 * 100 = 83.33
Which is 83% to the nearest whole number percentage
