Find the highest common factor of 80 and 20

20

Step-by-step explanation:

The Greatest Common Factor (GCF) for 20 and 80, notation CGF(20,80), is 20. Explanation: The factors of 20 are 1,2,4,5,10,20; The factors of 80 are 1,2,4,5,8,10,16,20,40,80.

20

Step-by-step explanation:

The factors of 20 are: 1, 2, 4, 5, 10, 20

The factors of 80 are: 1, 2, 4, 5, 8, 10, 16, 20, 40, 80

Then the greatest common factor is 20.

maximum area = xy = (16)(32) = 512 ft2

to maximize the area of the garden, the side of the fence parallel to the side of the house should be 32 ft long, and the other two sides should both have length 16 ft.'

in geometry, parallel lines are lines in a plane which do not meet; that is, two lines in a plane that do not intersect or touch each other at any point are said to be parallel. by extension, a line and a plane, or two planes, in three-dimensional euclidean space that do not share a point are said to be parallel.
