What are the zeros of the quadratic function f(x) = 6x^2 + 12x – 7?

Answers

Answer 1

Answer: 6x^2 + 12x – 7 = 0

Use the quadratic formula:

$x= (-b +/- √(b^2 -4ac) )/(2a)$

$\frac{-12+/- \sqrt{ 12^(2) -4(6)(-7)} }{12} = (-12+/-17.66)/(12)$

x = 0.47 and x = -2.47

What is the ratio?

Ratio is the analytical tool that helps in determining the proportion of one variable over the another. It helps in taking decisions such as business decisions, construction decision, and many more.

Computation:

ratio =side of B/side if k is the ratio =sideof B/side of A=3

The area is multiplied by:

k²=9Volume by k^3=27

27*32=864 (m^3)

The volume of Box B is 864m^3, when the dimension of box B is triple the dimension of box A.
