Question

Evaluate the expression when X = 19 and Z = five

Answer 1

Question:

Solution:

Consider the following rational expression:

`(x+z^2)/(x-3z)`

if we evaluate this expression at x=19 and z=5, we get:

`(19+(5)^2)/((19)-3(5))\text{ }`

this is equivalent to:

`(19+25)/(19-15)=(44)/(4)=11\text{ }`

So that, we can conclude that the correct answer is:

`11`
