Answer:
x^2 + 18x + 81
Step-by-step explanation:
(x+9) (x+9)
then distributive property
I think its B but ima have to check again and get back to you
V = (4/3)×3.14×(1.5^3)
V = 14.1 in^3
I'm not sure but I think it is false.
Ok, let's use N and N'.
N is (-1,-1). N' is (4,6).
From point N, the quadrilateral moves to the right 5 and up 7.
So, N+(5,7)=N'.
