Answer:
Step-by The scale factor is the ratio that determines the proportional relationship between the sides of similar figures. For the pairs of sides to be proportional to each other, they must have the same scale factor. In other words, similar figures have congruent angles and sides with the same scale factor.-step explanation:

Step-by-step explanation:
<u>Step 1: Define</u>
d(x) = 5x - 12
d(-4) is x = -4
<u>Step 2: Evaluate</u>
- Substitute in <em>x</em>: d(-4) = 5(-4) - 12
- Multiply: d(-4) = -20 - 12
- Subtract: d(-4) = -32
9-8.2-(-1.9) =
9-8.2+1.9
.8+1.9
2.7
-8-(-5.4)-1.8 =
-8+5.4-1.8
-2.6-1.8
-4.4
