Answer:
1 both are correct 2g(x) = (x + 3)(x + 2)(x − 3)
Step-by-step explanation:
AB=6cm AC=12cm
AC² = AB + BC²
12² = 6² + CB²
CB² = 12² - 6²
CB² = 144 - 36
CB² = 108
CB = √ 108 cm.
sin 55° = CB / CD
0.81915 = √108 / CD
CD = 10.392 / 0.81915
CD = 12.686 cm
B.
a = 2.828
b = 2.800
c = 2.288
d = 2.288
Answer: 600
