70=3x+10
Subtract 10 from both sides
60=3x
Divide both sides by 3
20=x
x=20
Answer:
Step-by-step explanation:
Volume of a cube:
V = a3
Surface area of a cube:
the area of each face (a x a) times 6 faces
S = 6a2
Face diagonal of a cube:
By the pythagorean theorem we know that
f2 = a2 + a2
Then f2 = 2a2
solving for f we get
f = a√2
Diagonal of the solid cube:
Again, by the pythagorean theorem we know that
d2 = a2 + f2
substituting f into this equation we get
d2 = a2 + (a√2)2 = a2 + 2a2 = 3a2
solving for d we get
d = a√3
Answer
in order to get the most correct answer you must plug the answer to get x
Answer:
Step-by-step explanation:
Let's consider the following expression.
We will use the Product of Powers Property. This property states that to multiply powers having the same base, we have to add the exponents.
The simplified expression is .
