Okay, lets start with number 1.
is also equal to (x+3)(x+3)(x+3)
If you take the first two ones and multiple them out it ends up with
or also know as 
You see to multiply them you take the first number in the first group of parenthesis and use the distributive property on the second equation, then you do the same this but with the second number in the first equation.
So once you have
you multiply it with your remaining (x + 3) using the distributive property to get 
I hope this helps you get the answers for the other two.
The question is missing important data. The quadrilateral having vertices A, B, C and D is a cyclic quadrilateral.
Answer:
B) 85°
Step-by-step explanation:
Given:
A cyclic quadrilateral with ∠A is 95° and ∠B is 105°.
For a cyclic quadrilateral, the sum of the opposite interior angles is equal to 180°
Therefore, sum of angles A and C is 180°.

Therefore, the correct option is option B) 85°
Answer:
Step-by-step explanation:
g(2)=2.2*(-5)
g(3)=2.2*(-5)^2
........................
g(n)=2.2*(-5)^(n-1)
Answer:
y = 129 degrees
Step-by-step explanation:
180 - 51 = 129
There are 6 possible outcomes on a dice. Meaning when you roll it it could be any of them. Because 3 is one of the 6 the answer would be 1/6
