Question

Evaluate rs+14srs+14sr, s, plus, 14, s when r=6r=6r, equals, 6 and s=\dfrac14s= 4 1 ​ s, equals, start fraction, 1, divided by, 4, end fraction.

Answer 1

Value of
`rs+14s` is, 5

Explanation:

Evaluate:

`rs+14s`

when, r = 6 and
`s = (1)/(4)`

Given that:

`rs+14s`

We can write this as:

⇒
`s(r+14)`

Substitute the given values we have;

`(1)/(4) \cdot (6+14)`

⇒
`(1)/(4) \cdot 20 = 5`

Therefore, the value of
`rs+14s` is, 5

Answer 2

For this case we have the following mathematical expression:

`rs + 14s`
Where, the variables of the expression are given by:

`r = 6 s = 1/4`
Substituting the variables in the given expression we have:

`(6) (1/4) +14 (1/4)`
Rewriting the expression we have:

`(6/4) + (14/4) = ((6 + 14) / 4) = 20/4`
Simplifying we have:

`20/4 = 5`
Answer:
When evaluating rs + 14s with r = 6 and s = 1/4, the result is 5.
