Answer:
C= 1/(2ax+2aw)
Step-by-step explanation:
C=1/2x(a+w)
Multiply a and w by 2x. Take note of the sign.
C= 1/(2ax+2aw)
when writing your answer, you don't need the brakets. I just put them so you'd understand that all those characters in the bracket are the denominator.

Answer:
-All integers are whole numbers.
-All rational numbers are natural numbers.
Step-by-step explanation:
Answer:
yes
Step-by-step explanation:
Using the converse of Pythagoras' identity
If the square of the longest side is equal to the sum of the squares of the other 2 sides then the triangle is right.
longest side = 15 , then 15² = 225
9² + 12² = 81 + 144 = 225
Thus the sail is a right triangle.
So in the problem, the length of the chord there is the circumference of the tree. So in order to get the diameter of the tree, we must use the formula in getting the circumference of a circle that is stated as follows.
C = 2pi *Radius
so first we need the get the radius of the tree which represent by this formula:
Radius = C /2pi = 8/6.2832 = 1.2732 ft
Diameter = 2*radius = 2 * 1.27 32 = 2.5465 feet
In summary, the diameter of the tree is 2.565 feet.
