Answer:
A or 3
Step-by-step explanation:
2/3+2/3=4/3 or 1 1/3
4/3+2/3= 6/3 or 2
Answer:
h(g(x))=h(3x^2+1)=2(3x^2+1)=6x^2+2
Answer:

Step-by-step explanation:
Given


Required
The length of the diagonals
First, calculate the length of AB using:

So, we have:




The diagonal of a square is calculated using:

Where x is the length of each side.
So:


-- approximated
12(2)+12(3)= (3+2) (12)= 5(12)=60
Associative Property...
(7+x)+3= 7+(x+3)
this is the correct one !!!
