Answer:
4 times bigger
Step-by-step explanation:
1. The area of an object dilated by a scale factor (SF) will be equal to (SF)^2.
2. For example, let's say the base and height of Triangle A is 4 and 8. The area would be 16 units squared. The base and height of Triangle B would be 8 and 16. The area would be 64 units squared.
3. As you can see from the aforementioned example, the SF (2) was squared and then multiplied by 16 to get 64.
Therefore, Triangle B's area is 4 times bigger than Triangle A's area.
The range is y values and domain is x values
y intercept here is 5 and since the function is increasing thus the range would be all real values bigger than or equal to 5
And the domain would be all real numbers.
Option B: 
is the correct answer.
Explanation:
The given expression is 
Simplifying the expression, we have,
Factor the equations, 
and 
,we get,
Substituting these factored expressions in the above expression, we have,
Cancelling the common terms 
and 
, we get,
Thus, the expression equivalent to is
Hence, Option B is the correct answer.
Answer: x=-3
Step-by-step explanation:
2x-4(x+3)=x-3
2x-4x-12=x-3
-2x-12=x-3. add 12 to both sides
-2x=x+9. subtract x from both sides
-3x=9. Divide both sides by -3
x=-3
