Question

w = (-3) . (-9), x = 3 + (-9), y = -3 x 9 , z = -3 + 9 If these are arranged in decreasing order of values, the correct sequence would be​

Answer 1

Step-by-step explanation:

(9)×(−3)×(−6)

As we know that

(−)×(−)=+

Therefore, on simplifying, we get

9×3×6

=(27×6)

=162

Answer 2

Answer:

w, z, x, y

Step-by-step explanation:

Here,

w = (-3) x (-9) = +(9 x 3)
  = 27

x = 3 + (-9) = -(9 - 3)

  = (-6)

y = (-3) x 9 = -(9 x 3)

  = (-27)

z = (-3) + 9 = +(9 - 3)

  = 6

Decreasing order = big to small
                             = 27, 6, (-6), (-9)

Therefore, the correct sequence = w, z, x, y
