Answer:

2x+y^2

Step-by-step explanation:

For this, you check to see if any of these variables are the same. There are two x's, and 2 y's. So, you have to multiply x and x, which gives you 2x, and since you multiply the y's it will give you y^2.

So the answer will be 2x+y^2

What is the answer to this math question?
oksano4ka [1.4K]

Answer:

The answer is option 3.

Step-by-step explanation:

First we have to find the area of both rectangle and triangle :

Rectangle,

area = base \times height

Let base = 9,

Let height = 3,

area = 9 \times 3 \\ area = 27 \:  {m}^{2}

Triangle,

area =  \frac{1}{2}  \times base \times height

Let base = 3,

Let height = 3,

area =  \frac{1}{2}  \times 3 \times 3 \\ area =  \frac{1}{2}  \times 9 \\ area =  \frac{9}{2}  \\ area = 4.5 \:  {m}^{2}

Lastly, in order to find the shaded region you have to substract the area of triangle from the area of rectangle :

area = 27 - 4.5 \\ area = 22.5 \:  {m}^{2}
