Which expressions are equivalent to -56z+28? Choose 2 answers.

Question

A. 1/2 x (-28z+14)

B. (−1.4z+0.7)

C. (14−7z)⋅(−4)

D.(8z−4)(−7)

E. −2(−28z−14)

Answer 1

D is correct

-56z + 28 = (8z-4)(-7) = -7(8z) -7(-4)

C is incorrect

(14-7z)(-4) = -56 +28z

A is incorrect

(1/2)(-28+14z) = -14+7z

B is incorrect -1.4z + .07

E is incorrect, correct except for one sign

-2(-28z -14) = 56z +28

if you had to choose two, D and E might be the "best" answer. Possibly the problem was misprinted or miscopied with one sign wrong for option E
