For what values of x is x2+2x=24 true?

-6 and -4
-4 and 6
4 and -6
6 and 4

Solve this equation using substitution. {4x + y = −2} {4x + 6y = 44}

In the figure below, ∠dec ≅ ∠dce, ∠b ≅ ∠f, and segment df is congruent to segment bd. point c is the point of intersection between segment ag and segment bd, while point e is the point of intersection between segment ag and segment df. the figure shows a polygon comprised of three triangles, abc, dec, and gfe. prove δabc ≅ δgfe.

If (x-2) 2= 49, then x could be a. -9 b. -7 c.- 2 d. 5 e.9
