—4 + (—19) can u help me plz

-23

Step-by-step explanation: Because when you are adding to negatives together, they add up forward, not backword.

7! = 7×6×5×4×3×2

3! = 3× 2

as 7! is multiple of 3! because 7! contains 3! that is 3× 2 as factor

so 7! /(3! ) = 7× 6× 5× 4

= 42 × 20

= 840

its b) 840✌✌✌
