Find the HCF of 120,140, 180​

The Highest common factor of 120,140,180 is  ( HCF) = 20

Step-by-step explanation:

Explanation:-

Given numbers  120,140,180

120 = 60 × 2

     = 30 × 2× 2

     = 15 × 2×2×2

    = 5×3× 2×2×2

140 =  70 × 2

      = 10 × 7× 2

      = 5× 2× 7× 2

180 = 90 × 2

      = 30×3×2

     = 5 × 6 × 3× 2

    = 5 × 2× 3× 2 × 3

The Highest common factor of 120,140,180 is   5 ×2×2 = 20

because 1.2 isnt half of 6 duh

answer: a) (0,0), (1,1), (2,8), and (3,27).

step-by-step explanation:

0^3=0

1^3=1

2^3=8

3^3=27

in effect, the exponential equation for this would me y=3^x. each x-coordinate cubed is giving the y coordinate, so a is your answer : )
