Question

Subtract: 2 (10b + 4) − (b − 2). (1 point)

Answer 1

To solve this problem, we will distribute the 2 to the terms inside the parentheses:

2(10b + 4) − (b − 2)

= 20b + 8 - (b - 2)

Now, distribute the negative sign to the terms inside the second parentheses:

= 20b + 8 - b + 2

Combine like terms:

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

= 19b + 10

So, the subtracted expression 2(10b + 4) - (b - 2) simplifies to 19b + 10.
