Perimeter- 28ft

N=11

Hey, do you remember the one I explained earlier? This one is really close to that. To find the area, you do the length times the width. This means

N*3

You already know the area so now, it’s

N*3=33

Divide both sides by 3 to get N alone and you get

N=11

Then, you have to find the perimeter by adding all of the sides. This means 3+3+11+11

This equals 28

The price of the book is $4. which expression can be used to show how much money the library will make if it sells 289 books

kogti [31]

If 1 book costs $4 then 289 books will make 289 times as much
so...
(price of book) x (number of books sold) = (amount of money made)
in this case...
4 x 289 = 1156

The square with a side length (x + 3) and an equilateral triangle with side lengths (3x-1) have the same perimeter what is the v

julia-pushkina [17]

Answer:

x = 3

Step-by-step explanation:

Side lenght of square = (x + 3)

Side length of equilateral triangle = (3x - 1)

It is Given that:

Perimeter of square = Perimeter of equilateral triangle

4 times side length of square = 3 times side length of equilateral triangle.

$\therefore \: 4(x + 3) = 3(3x - 1) \\ \\ \therefore \: 4x + 12 = 9x - 3 \\ \\ \therefore \:12 + 3 = 9x - 4x \\ \\ \therefore \:15 = 5x \\ \\ \therefore \:x = \frac{15}{5} \\ \\ \huge \red{ \boxed{\therefore \:x = 3}}$
