Step-by-step explanation:
Given


Solving (a): (s + t)(x)
This is calculated as:


Collect like terms


Solving (b): (s - t)(x)
This is calculated as:


Collect like terms


Solving (b): (s . t)(1)
First, we calculate (s.t)(x)
This is calculated as:

So, we have:

Substitute 1 for x



There are no graphs attached, so I punched the equation into a calculator and this is what it gave me!! I hope this helps
