A. 8m – 38

B. 8m + 7

D. 2m – 38

Answer 1

Okay lets try and solve. So first we will distribute 6(2m - 1).

What do you get when you do this?

Answer 3

Okay well you first do 6 * 2m, which is 12m and then times 1... so you should get:

6m - 6.

and then do the same to the next part so you should get:

(6m - 6) - (4m + 32)

Answer 4

Now when you combine like terms you should get 2m - 38.

Answer 6

Jason writes an expression equivalent to –2 + 5(d + 1) – 6d. His work is shown below.

–2 + 5(d + 1) – 6d
Step 1: 3(d + 1) – 6d
Step 2: 3d + 3 – 6d
Step 3: (3 – 6)d + 3
Step 4: –3d + 3

In what step does Jason first make an error, and what is his error?
