Answer: 4x + 21 or 7 - 10x or - 7x^2 - 3x + 7

not sure based on how the question is worded but it could be either 4x + 21 or 7 - 10x or - 7x^2 - 3x + 7

Step-by-step explanation:

option 1

7x + 3 (7-x)

= 7x + 21 - 3x

= 4x + 21

option 2

7 - (7x + 3x)

= 7 - 10x

option 3

7 - (x (7x + 3))

7 - (7x^2 + 3x)

-7x^2 - 3x + 7
