B I think??? Because in the first paragraph and last they all compare about how long it took and how good.
Answer:
6x^2 -4x +8
Step-by-step explanation:
(6x^2+ 5) - (4x - 3)
Distribute the minus sign
(6x^2+ 5) - 4x + 3
Combine like terms
6x^2 -4x +8
Answer:
Step-by-step explanation:
A) either radius or diameter and height
V = πR²h or πD²h/4
B) Radius is half a diameter, R = 4 cm
C) Rather depends on how they are put together.
Placing the rectangular faces touching would make a cylinder
D) V = 3.14(4²)(2) = 100.48 ≈ 100 cm³
E) divide by 2
i.e. V = ½πR²h
F V = ½(3.14)(4²)(2) = 50.24 ≈ 50 cm³
Answer:
8.9 meters per second I think.
Step-by-step explanation:
