If there are 27 posts, then there are (n - 1) total spaces between the posts . . . 27 - 1 = 26 total spaces (since there has to be a post at each end of the line)
Here's an example of 7 posts equally spaced . . . so you can see there are one less spaces between posts than there are posts (i.e. 6 total spaces between 7 posts) . . .
[] . . . [] . . . [] . . . [] . . . [] . . . [] . . . []
27 posts = 27*(10cm) = 270 cm = 2.7m
26 spaces = 26*(30m) = 780 m
<u><em>Length of Fence = L = 780m + 2.7m = 782.7m</em></u>
I assume that this is a sequence and you need to find the next number in the sequence.
The first two numbers are give as 133 and 142, we can get the difference between them by subtraction as follows:
142 - 133 = 9
This means that adding 9 will generate the next term as follows:
133
133+9 = 142
142 + 9 = 151
This means that : n=151
X+y=48
2x+y=86
Because the first one is the amount and the second one is the cost
Answer:
=−4m+19
Step-by-step explanation:
To find g (f(x)) you should substitute "4x^2+x+1" to "x" of g(x) function. You'll havew:

To count (4x^2+x+1)^2 Just assume ( [4x^2+x] + 1)^2 and use the (a+b)^2=a^2+2ab+b^2 formula, where a=4x^2+x and b=1
