Which shows the correct substitution of the values a, b, and c from the equation 0=-3x^2-2x into the quadratic formula

a = -3

b = -2

c = 0

Step-by-step explanation:

This is the same as 0=-3x^2-2x+0.

The quadratic formula uses ax^2+bx+c.

The coefficient of x^2 is -3, so a = -3. The coefficient of x is -2, so b = -2. Finally, the constant term is 0, so c = 0.

step-by-step explanation:

given that there are two triangles j'k'l' and jkl>

the former is got by dilating the second one.

when drawn on a grid, (graph paper) coordinates of vertices of first triangle is

(6,12)j, (9,6)k and (12,9)l

side jk has length = distance between j and k

=

side j'k'=distance between j' and k'

=

ie j'k'l' has sides 1/3 of that of corresponding sides of jkl.

hence scale factor of 1/3 is used to get j'k'l'from jkl
