Which expression is equivalent to 4 ( x + 1 ) – 7 ( x + 3 ) ? a. 11 x + 25 b. 11 x − 17 c. − 3 x − 17 d. − 3 x + 25

C. − 3x − 17

Step-by-step explanation:

4(x + 1) - 7(x +3)

Distribute:

4(x + 1) = 4x + 4

4 · x = 4x

4 · 1 = 4

- 7(x + 3) = - 7x - 21

-7 · x = -7x

-7 · 3 = -21

4x + 4 - 7x - 21

4x - 7x + 4 - 21

-3x - 17

look a the sides they are perpendicular
