Area is length x width.
With this one, what we have to do is work out the area of the larger square and the smaller, inside square, and take one from the other.
The larger one is 14 x 14 = 196.
The smaller one is 8 x 8 = 64
So, 196 - 64 = 132m²
Answer:
12%
Step-by-step explanation:
Percentage increase of something is often represented in a formula of a format like this:
X=Ar^t
Where X represents the total amount after t years.
A or 87000 in this case represents the starting value, which is this case is the starting population of the town. r or 1.12 represents the percentage increase, if it increases by 12% than the next year has 1.12 times as many people as the previous year so this is represented by 1.12 rather than say 0.12 which would indicate a 88% decrease instead. t is the time, no. of years in this case, that has elapsed since 1996.
This formula basically means that a town population of 87000 increases by 12% for every year of time that elapses.

Answer:
The nth term for the given sequence can be written as:
Step-by-step explanation:
Notice that this arithmetic sequence is created by adding to each term a common difference of 6 units:
7 + 6 = 13
13 + 6 = 19
19 + 6 = 25
Then, using the general expression for the nth term of an arithmetic sequence of first term "
" and common difference "<em>d</em>" we can write the nth term as:
which in this case translates as:
Answer:
(2b, 2b + 7).
Step-by-step explanation:
y = x + 7 and x = 2b ,
therefore y = 2b + 7.
