The correct answer is the first option.


If you want to use elimination, you can sum the two equations for example, so that the x's simplify:


(-2x+4y)+(2x+2y) = 16+8


6y = 24


y = 4


Plug this value for y in one of the equations to derive the value of x:


2x+2y=8 \implies 2x + 8 = 8 \implies x = 0


So, the solution is (x,y) = (0,4)

Which choice is true for a square?
liq [111]

Answer: A

Step-by-step explanation:

A rhombus is a quadrilateral with all sides equal in length. A square is a quadrilateral with all sides equal in length and all interior angles right angles. Thus a rhombus is not a square unless the angles are all right angles. ... A square however is a rhombus since all four of its sides are of the same length.

A square is a quadrilateral with all four angles right angles and all four sides of the same length. So a square is a special kind of rectangle, it is one where all the sides have the same length. Thus every square is a rectangle because it is a quadrilateral with all four angles right angles.

The area of a rectangle is 24 square centimeters. The length (X), in centimeters of the rectangle is given by the equation x2 +
Allisa [31]

The length of the rectangle is 3 cm

<h3>Applications of Quadratic equations</h3>

From the question, we are to determine the value of the length of the rectangle

To find the length of the rectangle, we will determine the value of x in the given equation

The given equation is

x^{2} + 5x =24

This can be written as

x^{2} +5x -24 =0

Factorizing

x^{2} +8x - 3x -24 = 0

x(x+8) -3(x+8)=0

(x-3)(x+8)=0

Then,

x-3 = 0 OR x + 8 = 0

x = 3 OR x = -8

Since, the length of the rectangle cannot be negative, the value of x is 3.

Hence, the length of the rectangle is 3 cm.
