Question

Which pair of expressions below are equivalent?" O 7(2x) and 9% 4(2x - 6) and 8x - 24 6 O 3x + 5x and 15x O x + x + x + x and x to the fourth power

Answer 1

O 7(2x) and 9x (FALSE)

7(2x) = 14x

______________

O 4(2x - 6) and 8x - 24 (TRUE)

4(2x -6) = 4*2 x -6*4

= 8x - 25

________________

O 3x + 5x and 15x (FALSE)

3x + 5x = (3 +5) x = 8x

_______________________

O x + x + x + x and x to the fourth power​ (FALSE)

x+ x + x + x + x = (1 + 1 +1 +1 + 1)x = 5 x

______________________

Answer

The second choice

O 4(2x - 6) and 8x - 24
