Answer:64
Step-by-step explanation:
i just know pemdas
It would be rounding the 5 to the 6 so it would be 6000 since the number next to 5 is bigger than 5.
I think is C or D, but I'm not to sure
First, you can section the polygon in the regular shapes.
Now, we can find the area of the bigger polygons. We will multiply 4x3 to get an area of 12 units^2. Then, we do 4x2 to get the area of the smaller polygon. This would be 8 units^2
12+8 is 20

Step-by-step explanation:
<u>First Degree Equations</u>
A first-degree equation can have one, none, or infinitely many solutions.
An equation like
2x + 3 = -x + 6
Has one solution: x=1
An equation like:
4x + 2 = 4x + 1
Has no solutions because when trying to solve for x we get:
2 = 1
This equality is false and no value of x can make it true
Finally, the equation:
3x + 2 = x + 2x + 2
Has infiniteyl many solutions, because when trying to solve it, we get:
2 = 2
Which is true regardless of the value of x
- The first given equation:
3x + 9 + 4x + x = ??
can be simplified as:
8x + 9 = ??
For this equation not having solutions, we should have 8x plus any number but 9 on the right side of the equation:
8x + 9 = 8x -3, or
8x + 9 = 8x + 4
- The second given equation:
3x + 9 + 4x + x = ??
can be simplified as:
8x + 9 = ??
If the equation has one solution, the only condition is that we should not have 8x on the right side. Thus any of those will do:
8x + 9 = 3x + 9
8x + 9 = -x + 5
8x + 9 = 0
3x + 9 + 4x + x = ??
can be simplified as:
8x + 9 = ??
For this equation to have infinitely many solutions, the right side must be exactly equal to the left side:
8x + 9 = 8x + 9
