The formula for the area of a square is:

A=s²

Since we known that the area is 81ft², we can solve for the length of a side.

A=s²
81=s²
find the square root of both sides
9ft=s

The length of each side is 9ft

All you need to do is find the square root of 81, because the formula for the area of square is s^{2}.

The square root of 81 is 9 ( 9 x 9 = 81)
To double check, plug 9 into the formula.
area = s^{2}
area = 9^{2}
area = 81

So, therefore, each side is 9ft.

Natali [406]

Hi!

6*7-27*9+64

42-27*9+64

42-243+64

Answer---->=-137

Explanation: <u><em>This question is super super easy to me. This question is about how to use their order of operations the math problems. First you had  to used PEMDAS stands for P-Parenthesis first, E-Exponents second, M-Multiply third, D-Divide fourth, A-Add fifth, and S-Subtract sixth.  Then multiply and divide from left to right  with 6*7=42. Then 27*9=243,42-243+64, and add or subtract from left to right with 42-243+64=-137 is the right answer. Hope this helps! And thank you for posting your question at here on Brainly. And have a great day. -Charlie</em></u>

A town's population has been growing linearly. In 2003, the population was 59.000 and the population has been growing by 1,700 p
Rudiy27

Answer:

In 2003, the population was 59000 and the population has been growing by 1,700 people each year.

A.

The equation will be:

59000+1700x = (population 'x' years after 2003)

For x, you plug in the amount of years after 2003.

Like if it is the year 2003, the population is 59000+1700(0)

= 59000

when it is year 2005, the population is 59000+1700(2)

= 62400

B.

The town's population in 2007 will be :

(2007-2003=4)

59000+1700(4)

Population = 65800

C.

59000+1700x=77700

=> 1700x=18700

x = 11

Means 2003+11=2014

Hence, by year 2014 the population will be 77700.
