Answer:

See below ~

Step-by-step explanation:

Finding the distance of each side length :

AB = √(3 - 0)² + (0 - 4)² = √9 + 16 = √25 = 5
BC = √(7 - 3)² + (3 - 0)² = √16 + 9 = 5
CD = √(4 - 7)² + (7 - 3)² = √9 + 16 = 5
DA = √(4 - 0)² + (7 - 4)² = √16 + 9 = 5
All sides are equal
Hence, it is a square

Perimeter :

4 x side length
4 x 5
20 units

Area :

(side length)²
(5)²
25 square units

A library contains 2000 books. There are 3 times as man non fiction books. Write and solve a systems of equations to determine t

icang [17]

Answer:

The number of fiction books is <u>500</u> and non fiction books is <u>1500</u>.

Step-by-step explanation:

Given:

Total book library contains = 2000.

There are 3 times as many non fiction books as fiction books.

Now, to determine the number of non fiction books and fiction books.

Let the fiction books be $x.$

And the non fiction books be $3x.$

Total books = 2000.

Now, to get the number of non fiction books and fiction books we put an equation:

$3x+x=2000.$

$4x=2000.$

Dividing both sides by 4 we get:

$x=500.$

Fiction books = 500.

Non fiction books = $3x=3\times 500=1500.$

Therefore, the number of fiction books is 500 and non fiction books is 1500.

Write and solve the system of linear equations described by the application and then answer the question. One hundred sixty feet

Lena [83]

Answer:

80 ft x 40 ft

Step-by-step explanation:

Let 'L' be the length of the longer side and 'W' be the length of the shorter side (or the width).

The equations that compose the linear system are:

$L+2W=160\\L=2W$

Solving the system:

$L+L=160\\L=80\\W=\frac{L}{2}\\W=40$

The garden is a rectangle with dimensions 80 ft x 40 ft.

doug had 2000 baseball cards. he wants at least "y" cards in his collection by the time he graduates. he buys 25 baseball cards

BabaBlast [244]

y≥25x+2000

because the +2000 is the y intercept ( where he started) and its 25x because he gets 25 over x amount of weeks
