Now, finding value of expression by sustituting value of "x" as given.
Surface area of the rectangular prism =
Surface area of the rectangular prism=
∴ Surface area of the rectangular prism=
Surface area of the rectangular prism=
∴ Surface area of the rectangular prism= 234 cm²
The answer is B, the green is f(x)=x^2 and the red one is g(x)=f(2x).
Answer:
We conclude that we must add 4² or 16 to complete the square.
Hence, option C i.e. 16 is the correct answer.
Step-by-step explanation:
We know that the perfect square formula is
<em>(a + b)² = a² + b² + 2ab</em>
Given the equation
Let us add 4² or 16 in the equation
as <em>(a + b)² = a² + b² + 2ab, </em>so
<em /><em />
<em />
Therefore, we conclude that we must add 4² or 16 to complete the square.
Hence, option C i.e. 16 is the correct answer.
