Answer:
A: 8/9
Step-by-step explanation:
1 3/5 = 8/5
8/5 x 2/3 x 5/6
16/15 x 5/6 = 80/90 = 8/9
80 divided by 10 = 8
90 divided by 10 = 9
The range is from 6 to 18.
Δ YX Z And Δ VUW are SIMILAR because all their respective angles are congruent:
∠ y = 90°; ∠ v = 90°
∠ x = 67°; ∠ u = 67°
∠ z = 23°; ∠ w = 23°
Two triangles are similar if their related angles are congruent (answer B)
(ab+3)(ab−3)
=(ab+3)(ab+−3)
=(ab)(ab)+(ab)(−3)+(3)(ab)+(3)(−3)
=a^2b^2−3ab+3ab−9
=a^2b^2−9
