Help please :) I would appreciate it if you also provided a explanation it's okay if there is none :))

Answer:

7x^2 + 7

Step-by-step explanation:

So you collect the "like-terms". 3x^2 is not the same as 7, however, 4x^2 has the same term as 3x^2, so you add those together and then join the 7 in the expression.

Hope that explanation makes sense

Am I finding the area of this wierd shape correctly if not what am I doing wrong?

saw5 [17]

Answer:

8 $ft^2$

Step-by-step explanation:

Sadly, you are doing this incorrectly.

The easiest way to find the area of this shape is to separate it into a square and a triangle.

This will leave you with a square with the dimentions 2x2 a triangle with a base of 4 and a height of 2.

The area of the square is 4 $ft^2$

Using the equation for the area of a triangle

$A=\frac{1}{2} bh$

We can plug in our 2 know values to get

$A=\frac{1}{2} (4)(2)\\A=4$

Now we can take the sum of the areas of these two shapes to get a total area of 8 $ft^2$
