E = mc2
is it a fact, hypothesis, theory, or law

answer: a.   one is a factor of every whole number since every number is divisible by itself.

180°

step-by-step explanation:

sum of equilateral triangle=180°

< n=60°

< m=120°°[angle supplementary of equilateral angle]

< m+< r+< x=360°(sum of exterior angle of triangle)

the answer to this would be 5x^3-6x^2-24 over 3x^2

hope this if needed hmu
