Simplest form of 2/10
slega [8]
To simplify fractions, all you have to do is divide both the numerator and the denominator by the greatest common factor of both integers.

In this case, the greatest common factor of 2 and 10 is 2.

2/2=1
10/2=5

So, 2/10 in its simplest form is 1/5.

Use f(x) = 2x-9 and g(x)=9-x^2 to evaluate g(f(3))​
Keith_Richards [23]

Answer:

g(f(3))​ = 0

Step-by-step explanation:

f(x) = 2x - 9

f(3) = 2(3) - 9

f(3) = -3

g(-3) = 9 - (-3)^2

g(-3) = 9 - 9

g(-3) = 0
