There are 12 such shapes. One can start with two squares, adding squares around the edge and rejecting shapes that have been previously seen. Repeating until you have 5 squares results in 12 distinct shapes.
_____
2 shapes are possible with 3 squares: L, I
5 shapes are possible with 4 squares: L, I, N, T, O
Answer:
The false statement is: They must occur under carefully controlled conditions found in a laboratory.
Step-by-step explanation:
Scientific experiments do not always occur in laboratories, also, in the case of social studies, the experiments are done under not controlled conditions to prove the hypothesis.
On the other hand, all scientific experiments must be well documented and they always give useful results (in case the hypothesis is rejected, future investigations will use other hypothesis).
Answer:

Step-by-step explanation:
We need to write the equation in slope-intercept form which passes through points (1/5,-4) and (16/5,-9)
Slope is given formula:

Now plug the value of slope m and any one of the given point into point slope formula:




Now simplify this and write in slope intercept form y=mx=b

Hence final answer is
