Is it 4 times x or 4 to the power of x, if the first one then, 8x-24x. if the second then 8^-6x
Answer:
The 2nd one/Green
Step-by-step explanation:
A plane figure with five straight sides and five angles.
3/k+3=8/k-2
butterfly (multiply 8 and k+3) and (multiply 3 and k-2) and set them = to eachother
8 (k+3)=3 (k-2)
distribute
8k+24=3k-6
-3k both sides
5k+24=-6
-24 both sides
5k=-30
÷5 both sides
k=-6
To find the diameter, divide the area(254.34) by pi(3.1415) and then square the quotient


That is the radius now just times that by 2 so 2 x 8.99 = 17.98
Now I have a felling the might be wanting 18 because 8.99 is so close to 9 and this is also true for 80.95. They probably want 80.95 = 81, which the square root of that is 9, which is the radius and if you times that by 2 the diameter would equal 18
