Step-by-step explanation:
B. <HIJ congruent to <JLK by SAS
D. <HIJ congruent to <LKJ by SAS
Similar triangles may or may not be congruent.
The true statement is: A. <HIJ congruent to <LKJ by ASA
The given parameters are:
The above highlights imply that:
This means that, the angle at point J in both shapes are also congruent.
By that, the two shapes have two congruent angles and one congruent side.
So, we can conclude that, triangles HIJ and LKJ are congruent by ASA theorem of similar triangles
Hence, (a) is true

The discriminant is 0. As the discriminant is 0 it will have equal roots.
And the real root is -2/3.
What is a Quadratic Equation?
In algebra, a quadratic equation is any equation that can be rearranged in a standard form where x represents an unknown, and a, b, and c represent known numbers, where a ≠ zero.
Conclusion: If a = zero, then the equation is linear, no longer quadratic, as there's no ax^2 term.
9+12x+4=0
a = 9 ; b = 12; c = 4;
discriminant = Δ = - 4ac
Δ = - (4*9*4) = 144 - 144 = 0
roots of quadratic equations are [ (-b ± √Δ)/ 2a)]
let roots of eqation are x1 & x2
As discriminant is zero so, x1=x2
x1 = x2 = -b/2a = - 12/(2*9) = -2/3

Answer:
hello :
9x^2+12x+4=0
a = 9 b = 12 c = 4
the discriminant Δ = b² - 4ac = 12² - 4(9) (4 ) =144 - 144 = 0
x1 = x2 = - b/2a = -12/18 = - 2/3
the real root is : - 2/3
