14d+21 and 7 (2d+3) choose yes or no to see if the expression is equivalent

Step-by-step explanation:

Yes they are equivalent.

14d + 21

7 (2d+3)

7 * 2d + 7*3

14d + 21

Yes - these answers are equivalent.

Step-by-step explanation:

In the expression 7 (2d+3), the 7 is outside the parentheses, meaning everything inside the parentheses is multiplied by 7.

2d X 7 = 14 d

3 X 7 = 21

7 (2d+3) = 14d + 21
