To solve this one-step equation you:
1. Substract 9 in both sides of the equation:
In this step is the mistake as Sara gets as result -4x=29 and the corret result of substract 9 in both sides of the equation is 5x=20.
2. Divide both sides of the equation into 5:
Then, the answer that Sara should found for the equation is x=4
Answer:
32
Step-by-step explanation:
31.54 = 32
Answer:

Step-by-step explanation:
f(x)=25-x^2 and g(x)=x+5
We need to find (f/g)(x)
(f/g)(x) = f(x)/ g(x)
we divide f(x) by g(x) and then we simplify

WE factor 25-x^2
25-x^2 = 5^2 - x^2 = (5-x)(5+x)


5+x or x+5 are same , so we cancel out x+5
