Which function is equivalent to y = 3(x + 2)2 + 7 ?

Troyanec [42]

Step-by-step explanation:

Our function:

$y = 3(x + 2)^{2} + 7$

Include the exponent:

$y = 3(x^{2} + 4) + 7$

Use the Distributive Property:

$y = 3 {x}^{2} + 12 + 7$

Add:

$\boxed{y = 3 {x}^{2} + 19}$

Where can I find the shaded area of this diagram?

erik [133]

To find the area of the figure, we divide it into two rectangles as follows:

And we find the area of each rectangle, which is given by:

$\begin{gathered} A=b\cdot h \\ \text{where b = base and h = height} \end{gathered}$

Area rectangle 1:

$A=3\cdot10=30m^2$

Area rectangle 2:

$A=4\cdot6=24m^2$

Therefore, the shaded area of the diagram is:

$A=30+24=54m^2$

Answer: 54 m^2
