Step-by-step explanation:
So, 3x^3 - 18x^2 - 9x + 132 = 0
The answer would be 
Exact Form: 4, 1 + 2 \3, 1 - 2 \3
Decimal Form:  4,4.6410161...., -2.46410161

In order to form a triangle, the third side must be at least greater than the difference of the other two sides
4 - 3 = 1 So the third side must be greater than 1 foot and the third side must be less than the sum of the other two sides
4 + 3 = 7 So, the third side must be less than 7
1 < third side < 7

Question 11a)
We are given side BC equals to side CE and angle CBA equals to angle CED
We also know that angle ACB equals to angle ECD are equal (opposite angles properties)
We have enough information to deduce that triangle ABC and triangle CDE are equal by postulate Angle-Side-Angle (ASA)
---------------------------------------------------------------------------------------------------------------
Question 11b)
We are given side AB equal to side ED, side BC equals to side EF, and side AC equals to side DF
We have enough information to deduce that triangle ABC and triangle DEF congruent by postulate Side-Side-Side (SSS)
----------------------------------------------------------------------------------------------------------------
Question 11c)
We are given side AC equals to side DF, angle ABC equals to angle DEF, and angle BAC equals to angle EDF
We have enough information to deduce that triangle ABC congruent to triangle DEF by postulate Angle-Side-Angle (ASA)
-----------------------------------------------------------------------------------------------------------------
Question 11d)
We do not have enough information to tell whether this shape congruent or not
