From the figure:
[Angle] [Given]
[Angle]
AA(Angle-Angle) similarity criterion states that in two triangles if two pairs of corresponding angles are equal, then these triangle Similar.
By AA similarity:
⇒
Answer:
(set up a ratio)
54/x = 18/100
(cross multiply)
18x = 5400
(solve for x)
x = 300 miles
Step-by-step explanation:
(x - 1)(2x + 3)
= 2x2 -2x + 3x - 3
= 2x^2 + x - 3
(2x - 3)(2x + 3) = 4x^2 - 9
so answer
(x - 1)(2x + 3) x - 1
------------------ simplifies to ------------------
4x^2 - 9 2x - 3
