Solve by using distributive property.

-3(m - 2) = 21

m=-5

Step-by-step explanation:

distribute -3: -3m+6=21

subtract 6 from both sides: -3m=15

divide by negative three: m=-5

m = -5

Step-by-step explanation:

-3(m-2)=21

-3m + 6 = 21

-3m = 15

         15

m =

         -3

m = -5

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✌✌✌
