Answer: well this is hard
Step-by-step explanation:
First of all you’re adding 7Y and you’re getting -8 and for subtracting you subtract 5why and you’re getting negative one so technically you’re getting different answers?
First your going to distribute the 3
3(-3x+15)
-9x+45
27=6x-9x+15
27=-3x+15
Then you’ll minus 15 from 27
27-15=12
12=3x
X=4
Answer:
Step-by-step explanation:
(−2x + 6y)(4x − 6y)
To multiply this we use FOIL method
first we multiply -2x with 4x, it becomes -8x^2
Then multiply -2x with -6y, we get 12xy
multiply 6y with 4x, we get 24xy
multiply +6y with -6y, we get -36y^2
Now we commbine all the answers we got
combien like terms
12xy+24xy= 36xy
