Answer:

x=126

Step-by-step explanation:

let 'x' represent the unknown number

(2/7)x + 9 = 45

Subtract 9 from both sides

2/7x=36

Because the fraction is being multiplied by 'x' we can multiply both sides by its reciprocal (because a fraction multiplied by its reciprocal is 1 which would 'eliminate' it from the left side therefore isolating 'x').

x=126

What are the solutions of 12 – x2 = 0?
Kruka [31]

Answer:

x = ± 2\sqrt{3}

Step-by-step explanation:

Given

12 - x² = 0 ( add x² to both sides )

12 = x² or

x² = 12 ( take the square root of both sides )

x = ±\sqrt{12}

  = ± \sqrt{4(3)} = ± 2\sqrt{3}

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
