This is the same as 6z+12 since adding two numbers can be done in any order.

Explanation:

The outer term is 2. The inner terms are 6 and 3z.

Use the distributive property to multiply the outer term by each inner term

2*6 = 12

2*3z = 6z

Then we add up the results to get 12+6z. We don't have any like terms, so we cannot combine them. We leave them as is.

your answer is 23/2 - 13.5

step-by-step explanation:

7/2 evaluates to

multiply x and 4.5

multiply x and 1

the x just gets copied along.

the answer is x

x

4.5*x evaluates to 4.5x

multiply 3 and 4.5x

multiply 1 and x

the x just gets copied along.

x

4.5*x*3 evaluates to 13.5x

7/2-4.5*x*3 evaluates to

  + 8 =

the answer is

7/2-4.5*x*3+8 evaluates to

the answer is 844

step-by-step explanation:

it is 844 because if you add 836.50 + 7.5 you will get 844
