First you can also remove parenthesis first.

And it gave us ⇒ [tex]4r*3+3r*4-(r*4+5r*3)[/tex], [tex]4r*3=12r[/tex],[tex]3r*4=12r[/tex], [tex]-(r*4+5r*3)=-19r[/tex], and [tex]=12r+12r-19r[/tex].

Finally, you add similar elements.

And it gave us ⇒ [tex]12r+12r-19r=5r[/tex].

Final answer is ⇒ [tex]\boxed{=5r}[/tex]

Hope this helps!

And thank you for posting your question at here on brainly, and have a great day.

Hey there!!

Given:

... 4r³ + 3r⁴ - ( r⁴ + 5r³ )

Let's write this equation as ...

... 4r³ + 3r⁴ -1 ( r⁴ + 5r³ )

Using the distributive property:

... 4r³ + 3r⁴ -1(r⁴) + (-1)(5r³)

... 4r³ + 3r⁴ - r⁴ - 5r³

Combining the like terms:

... 4r³-5r³-r⁴+3r⁴

... 2r²-r³ Is the answer.

Hope my answer helps!
