Given:
The equation of a straight line is
The x value of a point on the line is 14.
To find:
The y value of this point.
Solution:
If a point (x,y) lines on line, then the equation of line must be stratified by that point.
We have, the equation of a straight line.
Putting x=14, we get
Therefore, the y-value is 6 when the x-value is 14.
Answer:
The approximate area is 35 square centimeters
Step-by-step explanation:
we know that
The cross section passing through the diagonal of opposite faces of the cube is a rectangle
so
the approximate area is equal to
where
b is the diagonal of a face
h is the length side of the cube
we have
substitute
