<h2>8 unit tiles should be added</h2>
Step-by-step explanation:
Function given is 
. We wish to add more unit tiles to the function so that it becomes a complete square.
Since the given function is of order 2, the side of the square will be order 1. Let us assume a general order 1 expression 
to be the side of the square.
As the function forms the square after adding some 
unit tiles, 
From comparision, 
∴ 8 more unit tiles are required to complete the square.
Answer:
steps below
Step-by-step explanation:
7, 11, 15, 19 ...
common difference (d) = 11-7 = 4
Recursive rule: A(n) = A(n-1) + d = A(n-1) + 4
Explicit rule: A(n) = A(1) + d * (n-1) = A(1) + 4 *(n-1) = 7 + 4 * (n-1) = 4n + 3
15th term: A(15) = 4 * 15 + 3 = 63
Answer:
C
You just split the equation, as the brackets are both same. If you take (x-6) out, it will leave you with 3x+8.
Therefore, (x-6)(3x+8) is the answer.
