Answer:
(x+6)(x+6)
(x+6)^2
Always remember this identity
(a+b)^2 = a^2 + b^2 + 2ab
So, Now take x=a , 6 =b
Substitute above values
x^2 + 36 +2(x)(6)
=x^2 +36 +12x
=x(x+12) +36
With dot plot if it’s symmetrical its the mean and MAD, so i think that.
5 (7 + 23)
(Use distributive property to solve)
1. 5*7 + 5*23
2. 35 + 115
3. 150
