It would be: k+3 = 10
subtracting 3 from both sides,
k+3-3 = 10-3
k=7
Start by putting two coins on each side of the scale. If one side is higher, then the light coin must be in that pair (use a second weighing to determine which of that pair is the lightest.)
If the initial weighing shows the two pairs to be even, discard those four and go to the three others. Put two of the coins on the scale - one on each side. If one side stays higher, that coin is your light one. If however they are equal, the final unweighed coin must be the lighter coin.
Converse of the alternate interior angles theorem states the postulate or theorem that proves that x is parallel to y.
Look at the slope in each equation. A neg. slope indicates that the function is decreasing. A pos. slope: increasing.
The area of a regular octagon is given by:
A = (4) * (L) * (ap)
Where,
L: side
ap: apotema
Substituting values we have:
A = (4) * (19) * (16)
A = 1216 square inches
Answer:
The area of a regular octagon with an apothem 16 inches long and a side 19 inches long is:
A = 1216 square inches
