6x=78

x=78/6

The length of a square is 4x-3. Find the area in terms of x

prisoha [69]

Answer:

The area of square in terms of x = 16x² -24x + 9

Step-by-step explanation:

It is stated in the question that the length of a square = 4x - 3

Formula to find the area of the square is

<h2 /><h2>Area = length²</h2><h2 />

Area = ( 4x - 3 )²

<em>by using ( a - b )² = a² + b² - 2ab</em>

here a = 4x and b = -3

So,

(4x)² + (-3)² - 2(4x)(3)

16x² + 9 - 2(12x)

16x² + 9 - 24x

16x² -24x + 9

The area of square in terms of x = 16x² -24x + 9
