-3 + 8n = -5
8n = -2
n =-1/4 or n =-0.25
This cube has 6 faces, and all side lengths are equal.
The volume of a cube with sides of length L is given by L^3.
The problem says that the volume is 7^3, which means that each side is 7
The surface area of a cube of length L is 6*L^2. Since L = 7, the surface area is:
6*7^2 = 6*49 = 294 cm^2
The answer is 50.24. First, take the diameter and divide it by two (4). Then, multiply it by itself (16). Lastly, multiply it by pi,(3.14).
The first answer is 112 because you multiply 9 by 7 to get 63 and then you multiply 16 by 7 to get 112. and the second one is 27 because 16 times 3 equals 48 so then you multiply 9 by 3 to get 27.:)
Two inequalities are equivalent if they have the same set of solutions.
x - 5 ≤ 6 - 5
x - 5 ≤ 1 |add 5 to both sides
x ≤ 6
