Answer :
Answer:
The required expression would be (a-4)x + (9-b)
Step-by-step explanation:
Given,
In the triangle,
Base = 4x + b,
Side = ax + 9
Since, Side - base = [tex](ax + 9) - (4x + b)[/tex]
[tex]=ax + 9 - 4x - b[/tex]
[tex]=ax - 4x + 9 - b[/tex]
[tex]=(a-4)x + (9-b)[/tex]
That is,
The base is (a-4)x + (9-b) shorter compared to the side.
