Select all the expressions that are equivalent to - 6 (3x - 7).

a.-18x - 7

b. 4 (3x + 5) - 2 (15x - 11)

c. 2x - 7 - 5 (4x - 7)

d. 4 - 10 (3x - 7)

e. 6 (3x + 7)

f.-2 (9x - 21)

A and B is the answer

Option b and option f

Step-by-step explanation:

-6 (3x - 7) = - 18x + 42 so we will check for of the given options if they are equal to this.

a. - 18x - 7 - --> NO

b. 4 (3x + 5) - 2 (15x - 11) = 12x + 20 - 30x + 22

= - 18x + 42 - --> YES

c. 2x - 7 - 5 (4x - 7) = 2x - 7 - 20x + 35

= - 18x + 28 - --> NO

d. 4 - 10 (3x - 7) = 4 - 30x + 70

= - 30x + 74 - --> NO

e. 6 (3x + 7) = 18x + 42 - --> NO

f. - 2 (9x - 21) = - 18x + 42 - --> YES

Therefore, options b and f are equivalent to - 6 (3x - 7).
