It is 4×3x + 4×10 = 12x + 40
you have to know the value of x in order to have a solid number
Where is the passage at or information before that?
You can use this formula: <span>vf^2=0+2(9.8)(M)
solve it out like so:
vf^2=0+2(9.8)(180)
vf^2=2(1764)
vf^2=3528
now, square both sides to cancel out the power of 2. you are left with:

Answer:
7.1 cm
Step-by-step explanation:
The diagonal of a cube connects two opposite corners.
You can use the diagonal of a cube in a right triangle in which it is the hypotenuse. The legs of the triangle are a diagonal of a face and an edge.
Let the length of the edge be s.
a^2 + b^2 = c^2
s = 7.1
Answer: 7.1 cm
Divide the long leg by the square root of 3 to find the short leg. Double that figure to find the hypotenuse.
