2 is Reflexive property
4 is (I don't remember the specific property of this)
Answer:
∠D = 56°
∠D = 180° - (35° + 89°) = 56°
Answer:

Step-by-step explanation:
We have been given two expressions
and

Now we need to find out least common multiple of these two expressions.
First we need to find out what is common factor of both expressions.
and

Least common multiple means find the expression which can be divided by both expressions.
15 and 6 both goes into 30
so 30 is part of LCM (least common multiple )
Now pickup the highest exponent of each variable.
So we get 
Hence required least common multiple is 
Answer:
its D

Answer:
Step-by-step explanation:
"For a polynomial, no matter how many terms it has, always check for a greatest common factor (GCF) first. Literally, the greatest common factor is the biggest expression that will go into all of the terms. Using the GCF is like doing the distributive property backward.
If the equation is a trinomial — it has three terms — you can use the FOIL method for multiplying binomials backward.
If it’s a binomial, look for difference of squares, difference of cubes, or sum of cubes.
Finally, after the polynomial is fully factored, you can use the zero product property to solve the equation."
