Answer:
C. c^2=a^2+b^2-2abcos(90°)
Step-by-step explanation:
This is the law of cosine.
Volume=10×1.5×2.5=37.5 cu ft. Weight of contents=37.5×0.64=24 pounds.
Answer:
12x - 1
Step-by-step explanation:
Distribute the 2 and 3:
2(3x - 5) + 3(2x + 3)
(6x - 10) + (6x + 9)
Add like terms:
12x - 1
So, the answer is 12x - 1
4x + 30 = 5x + 20
30 - 20 = 5x - 4x
10 = x <==
