Answer:
100+10n
Step-by-step explanation: a(10)
100+10(10)
100+100 = 200
That’s the answer to your question.
Step-by-step explanation:

Let 'a' be the point and 'A' be the reflection of point 'a' through line x= -3
we know, (a+A)/2 (mid point of line aA) should lie on line x= -3
so by using this, we calculate vertices of reflected shape of MAST, we get
(-3,-1), (-3,2),(-5,3) and (-7,1)
