    • 15x + 16 = 0

To find:
    • Value of 15|x|

Approach and Working:
    • 15x + 16 = 0
      o x = \(\frac{-16}{15}\)
      o |x| = \(\frac{16}{15}\)
      o 15|x| = 16

Hence, the correct answer is option D.

Answer: D

for 15x + 16 = 0
x=-16/15
so lxl15 = 16

15x + 16 = 0 and we need to find the value of 15|x|

15x + 16 = 0 => 15x = -16

15|x| = |15x| = |-16| = 16

So, answer will be D
Hope it helps!

15x + 16 = 0

This is when 15x = -16.

=> 15|x| = |15x| = |-16| = 16

Answer D
