Answer:
179/180
Step-by-step explanation:
<em><u>Step One</u></em>
Find the prime factors of 18 and 20
18:3*3*2
20: 2 * 2 * 5
<em><u>Step Two</u></em>
You need two 2s two 3s and one 5 for the common denominator
The common denominator is 2 * 2 * 3 * 3 * 5 = 180
<em><u>Step Three</u></em>
Put the two fractions over 180
179/180
• f(x+3) = 4x + 12, you can factorize 4x + 12 like this:
Like this you can replace x+3 for and you will get the formula you need for f(x):
•
since the radicand can only be 0 or a positive number, x+4 and x-9 must both be 0 or positive
and
with this we know that x has to be:
and the domain is: [9,∞)
