which proportions show that the triangles are not similar?

answer:

(a) and (c)

step-by-step explanation:

in δabc, ab=1, ac=bc=2 and δdef, de=3, df=7 and ef=6

now, (a)

hence the given triangles are not similar.

(b)

=

hence,the triangles are similar.

(c)

hence, the triangles are not similar.

(d)

=

hence, triangles are similar.

hence, option a and c shows that triangles are not similar.

3x^2−4x+3 = x^2+x+1 2x^2−4x+3 = x+1        subtracingt x^2 from both sides 2x^2−5x+3 = 1            subtracingt x from both sides 2x^2−5x+2 = 0             subtracingt 1 from both sides (x-2)(x-1/2)=0             factoring the equation x=2 or x=1/2
