30= 3*10
30= 3*2*5
48= 12*4
48= 3*4*4
48= 3*2*2*2*2
60= 3*20
60= 3*10*2
60= 3*2*5*2
The GCF is 3*2 because all 3 numbers contain a 3 and a 2 in their prime factorizations.
Final answer: 6
Al you have to do is add 4 to the equation
This gives you g(x)=4x^2+9 which is your answer

Answer:
x=-10 and y=1
Step-by-step explanation:
-2(-10)=20
-10(1)=-10
20-10=10
Answer:
The step 4 is not what he should have done. But the wrong is step 5, because if he added -2x both sides, it would give the following equation:

and not 
Note that in step 4 he should have added 2x and not -2x to both sides, but we still have the equality. The problem is that step 5 is totally wrong.
I don't know what answer is expected to this question, but I would mark step 5, because this is mathematically wrong.
Solving the equation

Using distribution

Add
both sides


Add 12 both sides

Divide both sides by 5
