Answer:
Step-by-step explanation:
Figure 1
- 3 = 4 - 1 = 2² - 1 = (1 + 1)² - 1
Figure 2
- 8 = 9 - 1 = 3² - 1 = (2 + 1)² - 1
Figure 3
- 15 = 16 - 1 = 4² - 1 = (3 + 1)² - 1
<u>The function is:</u>
0.3×8=2.4
1.5×3=4.5
(2.4+4.5)+36=42.9
If Sara owns one more than twice as many books that Franks has then she has twice as many plus one more. Say Frank has 12 books, multiply that by 2 and then add 1.
Your equation should look like this: S= 1 + 2x
