Answer:
What is it?
Step-by-step explanation:
Answer:
Step-by-step explanation:
We are given that K is the midpoint of JL. Using this information, we want to find JL.
By the definition of midpoint, this means that:
Substitute them for their equations:
Solve for <em>x.</em> Subtract 8<em>x</em> from both sides:
Add 1 to both sides:
And divide both sides by 6. Hence:
JL is the sum of JK and KL. Hence:
Since JK = KL, substitute either one for the other:
Substitute JK for its equation:
Since we know that <em>x</em> = 2:
Thus:
Answer:
All the 3 expressions are equivalent.
Step-by-step explanation:
1/2 ( x + 4 )
= x/2 + 4/2
= x/2 + 2
x/2 + 2 is same as 2 + x/2
Answer:
5.07
Step-by-step explanation:
The volume of a cube is it's side length squared.
We can represent the side length as x.
x^3=130.
Then, taking the cubic root,
x=5.07
