Subtract: 2(10b+4)−(b−2) .

To subtract 2(10b+4)−(b−2), first apply the distributive property by multiplying 2 by each term inside the parentheses:

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

Now we can rewrite the expression as:

20b + 8 - (b - 2)

To subtract the expressions inside the parentheses, distribute the negative sign to each term within the parentheses:

20b + 8 - b + 2

Now combine like terms:

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

simplifies to:

19b + 10

To subtract (3g−4)−2(3g+4), first apply the distributive property by multiplying 2 by each term inside the parentheses:

2(3g + 4) = 6g + 8

Now we can rewrite the expression as:

(3g - 4) - (6g + 8)

To subtract the expressions inside the parentheses, distribute the negative sign to each term within the second set of parentheses:

3g - 4 - 6g - 8

Now combine like terms:

(3g - 6g) + (-4 - 8)

simplifies to:

-3g - 12

Subtract: (3g−4)−2(3g+4)

To subtract the expression 2(10b+4)−(b−2), we will simplify each term and combine like terms.

Step 1: Distribute the 2 to both terms inside the parentheses:
2(10b+4) = 20b + 8

Step 2: Distribute the negative sign to both terms inside the parentheses:
-(b−2) = -b + 2

Now, we can combine the simplified terms:

20b + 8 - (-b + 2)

Step 3: When subtracting a negative number, we can rewrite it as addition:
20b + 8 + b - 2

Step 4: Combine like terms:
(20b + b) + (8 - 2)

Step 5: Simplify:
21b + 6

Therefore, the final simplified expression is 21b + 6.

To subtract the given expression:

2(10b+4)−(b−2), we need to distribute the 2 through the first parentheses first:

2 * 10b = 20b
2 * 4 = 8

Therefore, the expression becomes:

20b + 8 - (b - 2)

Now, we can remove the parentheses by changing the signs inside the parentheses:

20b + 8 - b + 2

Next, we combine like terms:

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

19b + 10

The final expression after subtraction is 19b + 10.
