Answer:

Don't know if you are still online but, I have an answer to 25. I got 5r-r^2-6

Step-by-step explanation:

I believe this equation is a polynomial equation where you combine like terms. When subtracting you distribute the negative first then combine the similar term, just like adding with an extra step involved. So you take 3r and 2r and combine them because (like mentioned), you combine the terms that are same. You add them and get 5r. Since -r^2 and six don't have  the same terms, they stay the same and you combine the terms and make in it into a simplfied polynomial sequence. 5r-r^2-6.

Hope this helped! Sorry it took so long! Haven't done this since last year.

42x ​5 ​​ y ​4 ​​ =(−7x ​3 ​​ y)(B)
gulaghasi [49]
This is my very own step-step solution:

Step 1:
<span>Rearrange the equation by subtracting what is to the right of the equal sign from both sides of the equation : </span>

               <span> 42*x^5*y^4-((-7*x^3*y)*(b))=0 
</span>Step 2:<span>Equation at the end of step  1  :</span><span>
 
               ((42•(x5))•(y4))-((0-(7x3•y))•b) = 0
</span>
Step 3:Pulling out like terms :  

  <span> 42x5y4 + 7x3yb</span>  =  <span> 7x3y • (6x2y3 + b)</span> 

The correct is: 7x3y • (6x2y3 + b) = 0 <span> </span>

Quick Side Note:
<span>Binomial can not be factored as the difference of two perfect cubes
</span>
I hope this helps a little!

Hope you have a great day!
