Subtract: 2(10b+4)-(b-2)

Answer 1

To simplify the expression, let's start by distributing the 2 to the terms inside the parentheses:

2(10b + 4) = 20b + 8

Now distribute the -1 to the terms inside the parentheses:

-(b - 2) = -b + 2

So the expression becomes:

20b + 8 - (b - 2)

Now let's simplify the expression further. We can remove the parentheses:

20b + 8 - b + 2

Combine like terms:

(20b - b) + (8 + 2) = 19b + 10

Therefore, 2(10b + 4) - (b - 2) simplifies to 19b + 10.
