Step-by-step explanation:
I cannot understand the question of first part so second part
Y - 3 + 5z
Putting values of y and z
6 - 3 + 5(3)
3 + 15
18
Answer:

Step-by-step explanation:
Let the greatest common factor of
such that
and they are not all equal to zero,
is the common divisor of
and
. Therefore,
and 
You can write


The greatest common factor of
is given as

and

This happens because
is upper bounded because if
then 
for all
. Therefore, the set
has the greatest elements.
Taking
such that 
You can note that
and 
Therefore, the greatest common factor is 
Note: 
The correct answer is 8
Because
In triangle ORB
OR=(OB^2-RB^2)^1/2
OR=(17^2-15^2)^1/2
OR=(289-225)^1/2
OR=(64)^1/2
OR=8
RB=AB/2 so I kept its value 15 and ^1/2 refers to square root
Answer:
Step-by-step explanation:
Add '-2a' to each side of the equation.
5a + -2a = -6 + 2a + -2a
Combine like terms: 5a + -2a = 3a
3a = -6 + 2a + -2a
Combine like terms: 2a + -2a = 0
3a = -6 + 0
3a = -6
Divide each side by '3'.
a = -2
Simplifying
a = -2
