Given :
let's solve for f(x) × g(x) :
therefore, correct choice is : D
Answer:
19.741
Step-by-step explanation:
Answer:
3x + 8y = 72
19x + y = 72
Step-by-step explanation:
dubbles = x
mimstoons = y
Standard form:
Ax + By = C
3x + 8y = 72
Top:
x / (x + 1) - 1 / x
= [x^2 - (x +1)] / x(x+1)
= (x^2 - x - 1 ) / x (x+1)
Bottom:
x / (x + 1) + 1 / x
= [x^2 + (x +1)] / x(x+1)
= (x^2 + x + 1 ) / x (x+1)
Now you have:
(x^2 - x - 1 ) / x (x+1)
----------------------------
(x^2 + x + 1 ) / x (x+1)
= (x^2 - x - 1 ) / x (x+1) * x (x+1) / (x^2 + x + 1 )
= (x^2 - x - 1 ) /(x^2 + x + 1 )
Answer:
x^2 - x - 1
---------------------
x^2 + x + 1
The most efficient way of finding the answer to this question is first reducing 10-24-26 and comparing it with the first 5 combinations for right-angled triangles:
First, reduce 10-24-26 by dividing it by the GCF (greatest common factor).
10-24-26 divided by its GCF, 2, is: 5-12-13
Now comparing it with the first 5 combinations for right-angled triangles:
1) 3-4-5
2) 5-12-13
3) 7-24-25
4) 8-15-17
5) 20-21-29
As you can see, number 2 is the same as our reduced example. Therefore, we know that 10-24-26 is a right triangle.
Hope this helps!
