bot whats Subtract: 2(10b+4)−(b−2

Answer 1

To simplify the expression, let's follow the order of operations (PEMDAS):

First, distribute the 2 to every term inside the parentheses:
2 * 10b = 20b
2 * 4 = 8

The expression becomes: 20b + 8 - (b - 2)

Next, use the distributive property again:
-(b - 2) = -b + 2

The expression now becomes: 20b + 8 - b + 2

Combine like terms:
(20b - b) + (8 + 2) = 19b + 10

Therefore, the simplified expression is 19b + 10.
