A square has a perimeter of 12x 52 units. which expression represents the side length of the square in units? x 4 x 40 3x 13 3x
d1i1m1o1n [39]

The expression which represents the side length of the square which has perimeter of 12x 52 units is 3x+12 units.

<h3>What is the perimeter of a square?</h3>

The measure of the boundary of the sides of a square is called its perimeter. The perimeter of a square is 4 times the side of the square.

P=4a

Here, (<em>a</em>) is the side of the square.

A square has a perimeter of 12x +52 units. The perimeter of a square is 4 times the side of the square. Thus, the side of this square is,

P=4a\\12x +52=4a\\a=\dfrac{12x +52}{4}\\a=\dfrac{4(3x +12)}{4}\\a=3x+12

Thus, the expression which represents the side length of the square which has perimeter of 12x 52 units is 3x+12 units.

Consider the following equation f(x)=(x^2+4)/(4x^2-4x-8)
kifflom [539]

<em><u>Question:</u></em>

Consider the following equation: f(x)=x^2+4\4x^2-4x-8 name the vertical asymptote(s)

<em><u>Answer:</u></em>

The vertical asymptotes are x = 2 or x = -1

<em><u>Solution:</u></em>

Given that,

f(x)=\frac{x^2+4}{4x^2-4x-8}

For vertical asymptotes, set the denominator to zero and then solve the quadratic equation

4x^2-4x-8=0\\\\Divide\ by\ 2\\\\x^2 - 2x - 4 = 0

Split\ the\ middle\ term\\\\x^2+x-2x-2=0\\\\Group\ the\ equation\\\\(x^2 + x) - (2x + 2) = 0\\\\Factor\ the\ common\ term\\\\x(x + 1) - 2(x + 1) = 0\\\\(x + 1)(x - 2) = 0\\\\Therefore,\\\\x + 1 = 0\\\\x = -1\\\\And\\\\x - 2 = 0\\\\x = 2

Thus the vertical asymptotes are x = - 1 and x = 2
