CscA = 1/sinA
CosACscA = cosA × 1/sinA = cosA/SinA = cotA
Substituting x = 3 into the first expression:
-4(3) - 8 = -12 - 8 = -20
Substituting x = 3 into the second expression:
-2(3 + 1) - 2(3 + 3) = -2(4) - 2(6) = -8 - 12 = -20
Answer:
b. 42.875 units³
Step-by-step explanation:
The volume of a cuboid is the product of its edge dimensions (length×width×height):
(3.5 units)(3.5 units)(3.5 units) = 3.5³ units³ = 42.875 units³
