Answer:
(3r-10) (r+8)
Step-by-step explanation:
3r-34r+80
The first step is to combine like terms
3r - 34r
is -31r
-31r+80
We cannot factor since 31 is a prime number and 80 is not a multiple of 31
If you mean
3r^2-34r+80
(3r-10) (r+8)
Well the first step would be to change each fraction into an improper fraction
8 3/4= 35/4, 2 1/2= 5/2 or 10/4, and 5 1/4= 21/4
Now multiply 35/4 by 10/4 and you get 350/16 but in simplest form it would be 175/8. Multiply that by 21/4 and you get 3,675/32 and change that into a mixed number. The answer would be 114 27/32
Answer:
