Suppose △abc≅△lmn . which other congruency statements are correct? select each correct answer. △bac≅△mln △cba≅△mnl △bca≅△nml △acb≅△lnm

The correct option are 1 and 4 .

Explanation:

It is given that , it means AB = LM, BC=MN, AC=LM, , \angle B=\angle M and \angle C=\angle N as shown in the figure.

All the possible way to write is given below,

So, the correct options are 1 and 4.

According to the second, it means and which is not exactly true, therefore it is not a correct option.

According to the second, it means and which is not exactly true, therefore it is not a correct option.

hello from mrbilldoesmath!

answer:

25x^2 + 90x + 84

discussion:

mn(x) = m(n(x)) = m( 5x + 9) =

(5x + 9)^2 + 3 =>

25x^2 + 90x + 9^2 + 3 =

25x^2 + 90x + 84                 (as 9^2 = 9*9 = 81)

which is the second choice

p.s.   i'll be on vacation from friday, dec 22 to jan 2, 2019. have a great new year!
