Answer:

x−14y

Step-by-step explanation:

(7x−8y)+(−6x−6y)

The "sum" is the result of addition

7x-8y-6x-6y

7x−8y−6x−6y

Remove parentheses

7x−8y−6x−6y

Identify like terms

7x−6x−8y−6y

Commutative property

7x−6x  

−14y

−8y−6y

​

Combine like terms

1x−14y

x−14y

Coefficient of 1 isn't needed

If you triple 4 and subtract to each day how many days until you have zero
Mrrafil [7]
Do you mean subtract two each day? If so...
4x3=12 and 12 divided by 2 is 6 so it would take six days to reach zero
or
you could manually subtract two from 6 each days as in 12-2=10 (1 day), 10-2=8 (2 days), and so on...

What is the value of n in the simplified expression? (4k7)3= 4n ·(k7) 3= 64k21
Nesterboy [21]
Given:
(4k⁷)³ = 4n(k⁷)³

Note that (aˣ)ⁿ = aˣⁿ

Expand the left and right sides.
4³k²¹ = 4nk²¹
Divide each side by k²¹.
4³ = 4n
Divide each side by 4.
4² = n
Therefore
n = 4² = 16

Answer: n = 16

Answer:

Answer choice B

Step-by-step explanation:

When you factor the equation, 12 only has 6x2 to equal the -12x. This means that you'll factor it into (3x-6)(x-2). When you set either of these equal to 0, the x value is 2.
