Which expressions are equivalent to −2.1 (−5.9) (−3.7)−2.1 (−5.9) (−3.7) ? select each correct answer.

a. −(2.1 5.9) (−3.7)−(2.1 5.9) (−3.7)
b. −2.1−(5.9 3.7)−2.1−(5.9 3.7)
c. −(2.1−5.9) (−3.7)−(2.1−5.9) (−3.7)
d. −(2.1 5.9 3.7)

Answer 1

I JUST TOOK THE TEST AND GOT A 100 IT WAS DRUM ROLL C

Answer 2

-(2.1) + (-5.9) + (-3.7) = -(2.1 + 5.9) + (-3.7) = -2.1 - (5.9 + 3.7) = -(2.1 + 5.9 + 3.7)
THerefore, options a, b and d are equivalent.
