Answer:
Answer A is correct.
Step-by-step explanation:
Please note the difference beteen f(x+3) and f(3).
So f(x + 3) means, where you see x in the equation, you substitute x+3. (This is a recursive entry).
f(x)= 2x² - 3
f(x)= -3 + 2x²
f(x)= -3 + 2* (x+3)²
f(x)= -3 + 2* (x+3) * (x+3)
f(x)= -3 + 2* (x² + 3x + 3x + 9)
f(x)= -3 + 2* (x² + 6x + 9)
f(x)= -3 + 2x² + 12x + 18
f(x)= 2x² + 12x + 18 -3
f(x)= 2x² + 12x + 15
So answer A is the correct answer

Answer:
19 in.³
Step-by-step explanation:
We have been given that Jay created a model of a building from two rectangular prism. One building has a volume of 15 Cubic inches. The model had a total volume of 34 in.³ We are asked to find the volume of the other building.
We know that total volume of model will be equal to sum of volume of two buildings.
Therefore, the volume of the other building is 19 in.³
Answer:
47.4 not rounded 47.38
Step-by-step explanation:
You divide 199 by 4.2 and get 47.4 and then you can multiply 47.38x4.2 and will get you 199
Answer:
12
Step-by-step explanation:
Ok, first write it as an equation, 3x-12=24. Next, you need to simplify, add 12 to each side, getting 3x=36. Lastly, subtract 3 from each side which gives you x=12
