U² + 6u - 27
u² + 9u - 3u - 27
(u - 3)(u + 9)
Answer:
13.3 cm
Step-by-step explanation:
Apply the Pythagorean Theorem:
hyp² = (2nd longest side)² + (shortest side)². Here the numbers are:
(24 cm)² = (20 cm)² + (shortest side)², or
576 - 400 = 176 = hyp²
Taking the square root of both sides, we get (shortest side) = 13.3 cm
Answer:
B.
Step-by-step explanation:
hope it helps :)
As, v=√2as
Squaring both sides,
v²=2as
∴ s= v²/2a
