Using a simple guess and check method, i started with the lowest common multiple of 3, and 27 (the total growth) and used 3. if you plug i the numbers, we will say a is the dwarf lemon tree, b is the semi-dwarf lemon tree, and c is the full lemon tree, you know 3times2 equals 6. if you triple 6 you get 18. so if A grew 3 inches , B had to have grown 6 inches, and C had to have grown 18 inches. add them all and you get 27. so the dwarf lemon tree grew 3 inches, semi dwarf grew 6 inches, the full size grew 18 inches.
Answer:
20
Step-by-step explanation:
<h2><em>Width=w
</em></h2><h2><em>Length=l
</em></h2><h2><em>Perimeter=p
</em></h2><h2><em>
</em></h2><h2><em>p=2w+2l
</em></h2><h2><em>l=20+w
</em></h2><h2><em>p=2w+20+w+20+w
</em></h2><h2><em>p=4w+40
</em></h2><h2><em>
</em></h2><h2><em>4w+40=160
</em></h2><h2><em>4w=160-40=120
</em></h2><h2><em>w=120:4=30
</em></h2><h2><em>w=30
</em></h2><h2><em>l=20+w
</em></h2><h2><em>l=20+30=50</em></h2>
The answer is 2/16 if you do the math with the numerators only.
The next three terms are: -3, 6, and 15
To get each new term, we simply add 9 to the last term. So we add 9 to -12 to get -3. Then we add 9 to -3 to get 6. Finally we add 9 to 6 to get 15
In other words,
first term = -12
second term = first term+9 = -12+9 = -3
third term = second term + 9 = -3+9 = 6
fourth term = third term + 9 = 6+9 = 15
This process repeats forever though we only need three terms in this case.
So that's why the answer is the three values -3, 6 and 15
