Answer:

You can use the scale factor to determine if a picture is an enlargement if the scale factor is greater than 1. If it is less than 1 like 0.9 then the picture would be a reduction because you would be multiplying the number by a number smaller than 1. Now if we have a scale factor greater than 1 let's say 3. Then the picture would be an enlargement because the number is greater than 1.

Consider the number set: 11, 12, 13, 14

KATRIN_1 [288]

Answer:

Answer c) (13)

Step-by-step explanation:

Begin with 3x+2x-45=20. Go through the steps of solving this for x.

Combining like terms, we get 5x = 65.

Dividing both sides by 5, we get x = 13.

Answer c) (13) is the correct answer/solution/root.
