Given y=(2x+3)2, choose the standard form of the given quadratic equation

katrin2010 [14]

$y=(2x+3)^2 = 4x^2 +12x +9$

Taking 4 out from first two terms, we will get

$y=4(x^2+3x)+9$

Now we divide the coefficient of x by 2 and add and subtract the square of the result, we will get

$y=4(x^2+3x+\frac{9}{4}-\frac{9}{4})+9$

Distributing 4

$y=4(x+\frac{3}{2})^2+9-9$

Cancelling 9

$y=4(x+\frac{3}{2})^2$

And that's the required standard form.

A cube has a volume of 36cm3. What is the length of one side of the cube

umka2103 [35]

Answer:

Approximately 3.3 cm

Step-by-step explanation:

The volume of a cube is given by

V =s^3 where s is the side length

36 = s^3

Take the cube root of each side

36^ 1/3 = s^3^1/3

3.301927249 = s

Approximately 3.3 cm
