Answer 3

is that x a variable? or are you saying "multiply" ?

Answer 4

a variable

Answer 5

the parenthesis imply multiplication

Answer 6

ok so what you do is multiply the outer -3x by each term inside

Answer 7

right, i did that. but I can't multiply because they're not like terms

Answer 8

right?

Answer 9

you'll have

-3x times 4d = ??
-3x times -5e = ??
-3x times -3f = ??

Answer 10

you can multiply terms that aren't like terms

example 2x times 3y = 6xy

Answer 12

ohh

Answer 13

that rule you're thinking only applies to adding and subtracting

Answer 14

oh right.

Answer 15

Ok, so it would be -12xd

Answer 16

+ 15xe

Answer 17

+ 9xf ?

Answer 18

-3x times 4d = -12xd
-3x times -5e = 15xe
-3x times -3f = 9xf

all three are correct

Answer 19

so, `-3x (4d - 5e - 3f )` is equivalent to `-12xd + 15xe + 9xf`
