Answer:
14
Step-by-step explanation:
When looking at a sequence, look at the difference between each number. If you look at the first 4 numbers, you will observe:
-6 + 5 = -1
-1 + 5 = 4
4 + 5 = 9
Therefore, the next number must be 9 + 5 = 14.
Sorry, I wish I could help but I don’t understand this.
I have a solution here to the same problem but a slight different given:
-1 x<=-1
ax-b -1<x<1
<span>2 x>=1
</span>
The solution is as follows:
<span>f(x) = {-1, x ≤ -1
...... { ax - b, -1 < x < 1
...... { 2, x ≥ 1
Then we must have:
lim(x-->-1) -1 = lim(x-->-1) ax - b
==> -1 = -a - b
==> a + b = 1
And we must have:
lim(x-->1) ax - b = lim(x-->1) 2
==> a - b = 2
So we need to solve the system of equations given by:
a + b = 1
a - b = 2
After doing so, you should get that:
a = 3/2
b = -1/2
By studying the solution above, you now have the ability to answer the problem on your own!

17 x 2 = 34
54- 34 = 20
20/2 = 10 which is the width of the garden
17+5= 22
22 x 10= 220feet = the new area
