<span>The question is about the side length of a copy of the dartboard. We know that the original dartboard has sides that measure 9 inches. We also have the scale factor 0.25. The ratio of the corresponding sides is called the scale factor. If we have the scale factor 0.25 it means that for 1 unit of the original figure there are 0.25 units of length of a copy. Therefore: x = 9 * 0.25; x = 2.25 in. Answer: The side length of the dartboard Boyd drew is 2.25 inches.</span>
Step-by-step explanation:
r - 18 = 27
r = 27 + 18
r = 45
...
1 = 1, 2, 3, 4, 5
4= 4, 8, 12, 16, 20
5= 5, 10, 15, 20, 25
Distribute the 5 into the polynomial to get 5a + 5b - a - b. Combine like terms to get 4a + 4b, your answer.
