Answer:

The quantity of negative 1 plus or minus square root 33 all over 3

Step-by-step explanation:

3x2+6x=8

3x^2+6x-8=0

Quadratic formula

x=-b +or-√b^2-4ac/2a

a=3

b=6

c=-8

x=-b +or-√b^2-4ac/2a

=-6 +or- √(6)^2 - 4*3*-8/2*3

=-6 +or- √36-(-96)/6

=-6 +or-√36+96/132

=-6 +or- √132/6

=-6 +or- 2√33/6

=-6/6 +or- 2√33/6

= -1 +or- √33/3

A rectangular block of metal is 0.24 m long, 0.19 m wide and 0.15 m high. If the metal block is melted to form a cube, find the
DanielleElmas [232]
<h3>Answer: approximately 0.19 meters long</h3>

The more accurate value is 0.18982439916059 but this value isn't exact

========================================================

Explanation:

The volume of this rectangular block is 0.24*0.19*0.15 = 0.00684 cubic meters.

If we had a cube of this volume, then it has some side length x such that x^3 = 0.00684

Apply the cube root to both sides. This is the same as raising both sides to the 1/3 power

x^3 = 0.00684\\\\x = \sqrt[3]{0.00684}\\\\x = (0.00684)^{1/3}\\\\x \approx 0.18982439916059\\\\x \approx 0.19\\\\

The side length of the cube is approximately 0.19 meters long
