Hello there! The value of x is 20 or -20

"20 or - 20" is one answer so you are supposed to answer 20 or -20, not choose only one.

Step-by-step explanation:

\large{ \frac{ {x}^{2} }{ {5}^{2} }  =  {4}^{2} }

First, we simplify 5² and 4²

\large{ \frac{ {x}^{2} }{25}  = 16}

Multiply the whole equation by 25 to get rid of the denominator.

\large{ \frac{ {x}^{2} }{25} (25) = 16(25)} \\  \large{ {x}^{2}  = 400}

Square both sides and solve the equation.

\large{ \sqrt{ {x}^{2} }  =  \pm{ \sqrt{400} }}

Also don't forget to write "plus or minus" symbol when we are solving a quadratic equation by squaring both sides.

\large{x = \pm{20}}

The perimeter of a rectangular pool is 326 M if the length of the pool is 87 M what is its width​
sveta [45]

Half the perimeter is equal to the length plus the width.

326 /2 = 163

Length + width = 163

87 + width = 163

Width = 163 - 87

Width = 76 meters

Whats x? i don’t understand
rewona [7]

Answer:

The letter "x" is often used in algebra to mean a value that is not yet known. It is called a "variable" or sometimes an "unknown". In x + 2 = 7, x is a variable, but we can work out its value if we try! A variable doesn't have to be "x", it could be "y", "w" or any letter, name or symbol. See: Variable.
