Step-by-step explanation:
0.0625
1/4 of a mile is 0.25
0.25 divided by 4 = 0.0625 each
Simplify 6 – 4x – 2 + x
Combine like terms:
6 - 2 = 4
-4x + x = -3x
-3x + 4, or (A) is your answer

Simplify 5 – 2x – 3 + x
Combine like terms:
5 - 3 = 2
-2x + x = -x
-x + 2, or (B) is your answer

Answer:
1) ΔACD is a right triangle at C
=> sin 32° = AC/15
⇔ AC = sin 32°.15 ≈ 7.9 (cm)
2) ΔABC is a right triangle at C, using Pythagoras theorem, we have:
AB² = AC² + BC²
⇔ AB² = 7.9² + 9.7² = 156.5
⇒ AB = 12.5 (cm)
3) ΔABC is a right triangle at C
=> sin ∠BAC = BC/AB
⇔ sin ∠BAC = 9.7/12.5 = 0.776
⇒ ∠BAC ≈ 50.9°
4) ΔACD is a right triangle at C
=> cos 32° = CD/15
⇔ CD = cos32°.15
⇒ CD ≈ 12.72 (cm)
