From the given statement the unknown number is found to be - 1
The given statements can written in algebraic form as follows;
the unknown number = x
the number is multiplied by 6 = 6x
four less than twice the same number = 2x - 4
then, from the given statement the final equation equation becomes;
6x = 2x - 4
This unknown number can be solved by collecting similar terms together;
6x - 2x = -4
4x = -4
divide through by 4

Thus, the unknown number is - 1

Answer:
5√2 Inches
Step-by-step explanation:
By definition of a square, all it's sides are the same measurement (typically signified by the variable <em>s</em> on all sides).
In a triangle (as with a intersection from one corner to the other (diagonal), It would create a right triangle. Remember, the two leg sides are the same measurement (typically placed as 1). There is one triangle side measurement rule:
1 , 1 , √2
Plug in the corresponding numbers to the corresponding units. the 5 inches is a side (not the hypotenuse), so it belongs in the 1:
1 x 5 = 5
1 x 5 = 5
√2 x 5 = 5√2
The measurement of it's diagonal (hypotenuse) is 5√2.
