Question

Which is a simplified form of the expression -2b – 3(2b + 1)?

Answer 1

Answer:

C

Step-by-step explanation:

We need to use the distributive property to expand this.

The property is:

a(b+c) = ab + ac

So, the part " -3(2b+1) " will becomes:

-3(2b+1) = (-3)(2b) + (-3)(1) = -6b - 3

So, the problem becomes:

-2b -3(2b+1) = -2b -6b -3

Now, we add like terms:

-2b - 6b - 3

(-2-6)b - 3

-8b - 3

This is the correct answer, answer choice C
