Step-by-step explanation:
1.24330900243
I did the whole equation on paper
16m^2 + 72m + 81
you expand it, by (9+4m)(9+4m), using distributive property you get
81 + 36m + 36m + 16m^2, simplifying you get the answer
Answer: 1st option
I've attached the solution
32
x^2 + 4y = 16 + 20 = 32
Just do substitution.
Hope this helps.
Good Luck
