Answer:</h3>
6 cm, 8 cm, 12 cm
<h3>
Step-by-step explanation:</h3>
The perimeter of the reference triangle is ...
... (15 +20 +30) cm = 65 cm
Then the similar triangle has a scale factor of ...
... (26 cm)/(65 cm) = 2/5
Multiplying the side lengths of the reference triangle by 2/5, we get ...
... {15 cm, 20 cm, 30 cm) × 2/5 = {6 cm, 8 cm, 12 cm}
These are the side lengths of the smaller similar triangle. (Check: their sum is 26 cm.)
A. 3.45%
The formula for a proportion is x/n, "n" is the total of objects and "x" is the number os successes. In this case "defective" is the success because you want to know the percentage for defective parts, so 4/116= 0.0345 and you have to multiply the result by 100 and you get your answer in percentage.

Sorry if I got that wrong
Answer:
Step-by-step explanation:
-6.6(3x+6)-1.7(2x-5)
open the bracket
-19.8x - 39.6 - 3.3x + 8.5
combine the like terms
-19.8x - 3.3x -39.8 + 8.5
-23.1x - 31.3
