Question

Which expression is equivalent to (2 + 4) (2x – 1) (2 + 3)?

a. 203 + 13.02 – 17 + 12

b. 2x³ + 13.02 + 2x² – 12

c. 2.03 + 13x² + 173 - 12

d. 2x³ + 13x² + 173 + 12

Answer 1

The expression (2 + 4) (2x – 1) (2 + 3) is equivalent to 60x – 30.

Step-by-step explanation:

To simplify the expression (2 + 4) (2x – 1) (2 + 3), we follow the order of operations: first, we add the numbers inside the parentheses, then we simplify the expression further.

(2 + 4) (2x – 1) (2 + 3) = 6 (2x – 1) (5)

Next, we can distribute the 6 to each term inside the second set of parentheses:

6 (2x – 1) (5) = 6 * 2x * 5 – 6 * 1 * 5 = 60x – 30

So, the expression (2 + 4) (2x – 1) (2 + 3) is equivalent to 60x – 30.
