Question

.Subtract: 2(10b+4)−(b−2

Answer 1

To simplify the expression, first distribute the 2 on the left side:

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

Now distribute the negative sign on the right side:

-(b-2) = -b + 2

Now the expression becomes:

20b + 8 - (-b + 2)

Next, remove the parentheses around -b + 2 (remembering to distribute the negative sign):

20b + 8 + b - 2

Combine like terms:

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

21b + 6

So, the simplified expression is 21b + 6.
