Julia is using the distributive property to simplify 3(x+2) find her mistake and correct it.

The answer is 3x+6

Step-by-step explanation:

You multiply what's on the outside of the parenthesis by everything on the inside, so you would do 3 times x and 3 times 2. They don't combine because they are like terms.

step-by-step explanation:

mean or average is 40.6

"image"

step-by-step explanation:

in most of these problems, the notation is that the point with a "prime" is the image of the point without. that is, b' is the image of b.

here, there is no dilation or reflection. there is simply translation (with no direction shown). which figure you call the "preimage" and which one you call the "image" is up to you. as a matter of convention, the naming is as described above.
