To factor 3x + 9 you should know that 3 is a common factor of both 3 and 9, so you can factor 3 out in both numbers like this.
3x + 9
3(x + 3)
When you factor out 3 on both numbers you should know that 3 X 3 = 9 and since you factored out 3 there would be another 3 left so you would have the answer: 3(x + 3)
Here is another equation that might help:
24x + 36
Since 12 is a common factor of both numbers, factor 12 out of the equation:
12 (2x + 3)
You know that 12 x 2 = 24 and that 12 x 3 = 36
And since you can't factor out anymore numbers because 2 and 3 doesn't have any common factors with each other you get the answer:
12 (2x + 3)

Answer:
Third graph from the top
Step-by-step explanation:
Formula for g(x) is g(x) = 3 · x∧2
When we replace x=5 in the formula we get:
g(5) = 3 · 5∧2 = 3 · 25 = 75

Answer:
<h2>52 ft.</h2>
Step-by-step explanation:
In this case, we need to calculate a perimeter, which is the sum of all sides of the rectangle.
So, rectangles has opposite sides equal, therefore, the perimeter should be:
; having L as the larger side.

Hence, the strip of wallpaper needs to be as least 52 ft.
