Hello! 3x + 20 and 8x - 5 are equal. To find the value of "x", we should set up and solve an equation. It would be written like this:
3x + 20 = 8x - 5
First off, subtract 3x from both sides in order to get 20 = 5x - 5. Add 5 to both sides to get 25 = 5x. Now, divide each side by 5 to isolate the "x". 25/5 is 5. Now, let's plug in the value and see if it works. 3 * 5 is 15. 15 + 20 is 35. 8 * 5 is 40. 40 - 5 is 35. 35 = 35. There. x = 5.
Answer:
The answer is 8.3 W + 17.4
If you click on the image it will show you how to solve the equation and I hope this helps you.

Answer:
9.6 cm
Step-by-step explanation:
Since the scale factor is 3 (you can figure that out by dividing the larger side of the triangle by the one on the smaller triangle that is the same side) you would divide all other sides by 3 to find individual lengths.
9.6/3 = 3.2
7.2/3 = 2.4
We already know the other side, 4.
3.2 + 2.4 + 4 = 9.6cm
