Question

What is the answer please 2(4 + 2z) =

Answer 1

Answer:

2(4 + 2z) = 8 + 4z

or

2(4 + 2z) = 0

z = -2

Step-by-step explanation:

How to solve:

2(4 + 2z)

Distribute:

2(4 + 2z)

2(4) + 2(2z)

Multiply:

2(4) + 2(2z)

8 + 4z

8 + 4z is the simplified expression.

How to solve:

2(4 + 2z) = 0

Distribute:

2(4 + 2z) = 0

2(4) + 2(2z) = 0

Multiply:

2(4) + 2(2z) = 0

8 + 4z = 0

Subtract 8 on both sides:

8 + 4z = 0

-8          -8

4z = -8

Divide by 4 on both sides:

4z = -8

/4      /4

z = -2

z = -2 is the answer if 0 is on the other side of the equal sign

Answer 2

Answer: It would be 8+4z  because you can't add a variable.
