Answer: D) 144 square cm</h3>
========================================================
Explanation:
A square has all four sides that are the same length. So all four sides are 12 cm
area = side*side = 12*12 = 144 cm^2
Or you could say
area = (side)^2 = (12)^2 = 144 cm^2
Squaring a number is the same as multiplying it by itself. Hence the name "square" refers to a side length pairing up with its corresponding area value.

Side note: The perimeter is 4*(side) = 4*12 = 48 cm. It's possible that choice B is put in there as a trick answer.
Answer:
(-16, 0) and (0,-12) are exactly two points on the graph of the given equation.
Step-by-step explanation:
Here, the given expression is : 
Here, let M(a) = b
⇒The equation becomes 
Now, check for all the given points for (a,b)
<u>1) FOR (-9,0)</u>

Hence, (-9,0) is NOT on the graph.
<u>2) FOR (-16,0)</u>
Here, LHS = b = 0
and
Hence, LHS = RHS = 0 So, (-16,0) is on the graph.
<u>3) FOR (0,12)</u>
Here, LHS = b = 12

Hence, (0,12) is NOT on the graph.
<u>4) FOR (0,-12)</u>
Here, LHS = b = -12

and LHS = RHS = -12
Hence, (0,-12) is on the graph.
Hence, (-16, 0) and (0,-12) are exactly two points on the graph of the given equation.
