(x+2)(x+1) = x^2 + x + 2x + 2
simplify it
x^2 + 3x + 2
the theorem is SAS that proves the two triangles are congruent
Answer:
2
Step-by-step explanation:
5x - 10 = 0
+10 +10
5x = 10
/5 /5
x = 2
K=-1 or k=5
either quantity could equal zero, so put each quantity equal to zero and solve for k.
hope this helps :)
