Which distance measures 7 units? a number line going from negative 8 to positive 8. a closed circle appears at negative 7 and is labeled l. a closed circle appears at negative 1 and is labeled m. a closed circle appears at positive 2 and is labeled n. a closed circle appears at positive 6 and is labeled p. an orange arrow line is above the number line with an arrow pointing left passed negative 7 and right passed positive 6. it contains all points.

not only in mathematics, scientific proof also are required in the other field of science. also maths proofs are of particular structure, containing steps and logics. so proving is like doing science, it is science. that's why it is important to prove. 

an inaccurate proof leads to errors, or stating results that are not accurate.  which wil mess the probelm up you dont want this

the answer should be:

a. 3, 4, and 6

b. 18, 24, and 36

c. 4.8, 6.4, and 9.6
