Evaluate 8r-rs8r−rs8, r, minus, r, s when r=6r=6r, equals, 6 and s=5s=5s, equals, 5.

Answer 1

`8r-rs=18` when r=6 and s=5.

Explanation:

Given : Expression
`8r-rs` when r=6 and s=5

To find : Evaluate the expression ?

Solution :

Expression
`8r-rs`

The value of r=6

and the value of s=5

Substitute in the expression,

`8r-rs=8(6)-(6)(5)`

`8r-rs=48-30`

`8r-rs=18`

Therefore,
`8r-rs=18` when r=6 and s=5.

Answer 2

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

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