Answer:
−8x+6y−12
Step-by-step explanation:
Distribute:
=(2)(4)+(2)(−2x)+(2)(y)+(−4)(5)+(−4)(x)+(−4)(−y)
=8+−4x+2y+−20+−4x+4y
Combine Like Terms:
=8+−4x+2y+−20+−4x+4y
=(−4x+−4x)+(2y+4y)+(8+−20)
=−8x+6y+−12
Answer:
the second description and and expression is correct
Step-by-step explanation:
the first one is wrong because it says 7 minus while it should be minus 7
If you want to add fractions, you need to first make them like fractions, this means both fractions need to have the same denominator without changing its proportion:
7/10 = 70/100

Now it is the same and you can add them now because they are like fractions.
70/100 + 17/100 = 87/100
