Answer:

5x^{2} -18x-8

Step-by-step explanation:

The formula for area of a rectange is lw, where l is length and w is width.  Since x-4 and 5x+2 are the sides, we can multiply them together to give us the area.  We do (x-4)(5x+2).  We use the FOIL method (First Outside Inside Last) and get 5x^2-18x-8.

If ΔEFG ~ ΔLMN with a ratio of 2:1, which of the following is true?
strojnjashka [21]

Answer:

  segment EF over segment LM equals segment FG over segment MN

Step-by-step explanation:

The triangles are similar, not congruent, so any answer choice with the word "congruent" can be ignored.

The sequence of letters in the triangle name tells you the corresponding segments:

  • EF corresponds to LM
  • EG corresponds to LN
  • FG corresponds to MN

Corresponding segments have the same ratio, so ...

  EF/LM = FG/MN . . . . . . matches the first answer choice

  EF/LM = EG/LN . . . . does not match the 3rd answer choice
