Question

Subtract: 2(10b+4)−(b−2) .(1 point)

Answer 1

To subtract 2(10b+4) - (b-2), we need to distribute the 2 to both terms inside the parentheses.
This gives us: 20b + 8 - (b - 2).

Next, we can remove the parentheses by changing the sign of each term inside the second set of parentheses: 20b + 8 - b + 2.

Now, we can combine like terms by adding or subtracting: 20b - b + 8 + 2 = 19b + 10.

The final answer is 19b + 10.
