Question

3m+4n-4(4m-6n)

Answer 1

first multiply the -4 through the expression (4m-6n)

Answer 2

Use the distributive property first, \[\large 3m+4n-4(4m-6n) =\]
\[\large 3m + 4n - 4(4m) - 4 (-6n)\]

Answer 3

12m+24n

Answer 4

:/

Answer 5

no, not quite

Answer 6

if you are doing

(-4)(4m) - 4*(-6n)

-16m + 24n

you got the 24 right, but the first term should be -16m

Answer 7

3m+4n-16m+24n Simplify that and you will have the answer

Answer 8

don't ignore the negative signs.. \[\large 3m + 4n - 4(4m) - 4 (-6n) = \] \[\large 3m + 4n - 16m + 24n = \]
\[\large (3m - 16m) + (4n + 24n) =\]

Answer 9

-13m+28n
