Question

22. The expression 3(-4b) - 2(a - b - c) is equal to which of the following expressions?

(1) -2a - 10b - 2c
(2) -2a - 10b + 2c
(3) -2a -5b + 2c
(4) -2a -4b - 2c
(5) 2a-4b - 2c​

Answer 1

We can simplify the expression as follows:

3(-4b) - 2(a - b - c) = -12b - 2a + 2b + 2c

Combining like terms, we get:

= -2a - 10b + 2c

Therefore, the expression 3(-4b) - 2(a - b - c) is equal to option (2), -2a - 10b + 2c.
