Answer: b, c, and e
Explanation: only those fit the requirements to be considered a mathematical sentence.
        
             
        
        
        
I think you're trying to say 6x^6-4x^5+9x-6. ^ Is a symbol that means the number after it is an exponent.
First step, find the gcf (greatest common factor) between the first two parts. The gcf of 6x^6-4x^5 is 2x^5.
Now take it out. You get
2x^5(3x-2)
If you expand that equation, you will get 6x^6-4x^5 which is why you know it's correct. 
Now do the same for the second half.
The gcf for the second two parts is 3.
3(3x-2)
Notice anything? Yep, in both of them, after you take out the gcf, you get (3x-2)
Now, you combine them into one equation
2x^5(3x-2)+3(3x-2)
Then you do this
(2x^5+3)(3x-2)
That's your factored form.
        
             
        
        
        
Answer:
The answer is 82 square feet
Step-by-step explanation:
An easy way to do this is to split it into two rectanlges. You can do 10*5 and 8*4 as the dimensions to the two rectangles or you can do 2*4 and 9*8.
I am going to do the first option.
The area of a rectangle is length times width. 
Rectangle one can be the one with the dimensions 10 and 5 and the length and width. 
Rectangle two can be the one with the dimensions 8 and 4 and the length and width. 
Area of rectangle one = 50 feet^2
Area of rectangle two = 32 feet^2 
Since we split a large irregular shape into two bits, we must add them together, which results in 82 feet^2.

Answer:
c is 30. 
The angles, from left to right, are: 
66, 94, and 20. 
Step-by-step explanation:
The three angles form a straight angle. In other words, they sum to 180. So, we can write the following equation: 

Let's solve for c. Combine like terms: 

Add: 

Subtract 15 from both sides: 

Divide both sides by 5.5: 

So, the value of c is 30. 
Now, substitute it into each of the angles to find their respective measures. 
Left-Most Angle: 
We have: 

Substitute 30 for c. This yields: 

Multiply and add: 

Middle Angle: 
We have: 

Substitute 30 for c: 

Multiply and add: 

Right-Most Angle: 
We have: 

Substitute 30 for c: 

Multiply and add: 

So, our angles, from left to right, are: 66, 94, and 20. 
And the value of c is 30. 
And we're done!
