Answer:
The greatest common factor (GCF) of 18 and 20 is 2.
Step-by-step explanation:
To solve this problem, first, you have to find the greatest common factor of 18 and 20.
Factors of 18:
1, 2, 3, 6, 9, and 18.
Factors of 20:
1, 2, 4, 5, 10, and 20.
So, the greatest common factor (GCF) of 18 and 20 is 2.
Answer: Yes
Explanation: a statement that the values of two mathematical expressions are equal (indicated by the sign =).
Two values (6 and 3) are being brought together for another value represented by the = symbol making this an equation
Answer: The coordinate of the center is (4,-3)
radius = 8
Step-by-step explanation:
Given ;

re - arranging , we have

comparing with the general equation

This means that



also




The coordinate of the center is (-g,-f)
Therefore;
the coordinate of the center = (4,-3)
the formula for calculating r is given by:




METHOD 2

using completing the square method , we have

completing the square , we have


comparing with the general equation

where a and b are the coordinate of the center , that is
the coordinate of the center is ( 4 , -3)


0.732
0.750
If you have trouble with decimals, then multiply both numbers by a constant number to get rid of the decimals. In this case, we would multiply by 1000.
0.732 x 1000 = 732
0.750 x 1000 = 750
Obviously, 750 is bigger than 732. Therefore, 0.75 is bigger than 7.32.
By the way, this is a property:
If

, then
