It appears you want to evaluate
  8r -r*s
for (r, s) = (6, 5).

That would be
  8*6 -6*5 = 48 -30 = 18

Answer:

[tex]8r-rs=18[/tex] when r=6 and s=5.

Step-by-step explanation:

Given : Expression [tex]8r-rs[/tex] when r=6 and s=5

To find : Evaluate the expression ?

Solution :

Expression [tex]8r-rs[/tex]

The value of r=6

and the value of s=5

Substitute in the expression,

[tex]8r-rs=8(6)-(6)(5)[/tex]

[tex]8r-rs=48-30[/tex]

[tex]8r-rs=18[/tex]

Therefore, [tex]8r-rs=18[/tex] when r=6 and s=5.
