Question

subtract 2 (10b+4)-(b-2)

Answer 1

To subtract the expressions 2(10b+4) from (b-2), we need to distribute the 2 to the terms within the parentheses first.

So, 2(10b+4) becomes 20b + 8.

Now, let's subtract (20b + 8) from (b-2):

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

= b - 2 - 20b - 8

= -19b - 10

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