1.6 feet
Step-by-step explanation:
The radius is 1/2 of the diameter.
0.8 * 2 = 1.6
It is one out of twelve, if the twelve sides have all numbers from 1-12
Answer:
x=5, -1
Step-by-step explanation:
set the equation equal to 0: 2x^2-8x-10=0
divide both sides by 2 to get x^2-4x-5=0
next factor your new equation to get (x+1)(x-5)
set those equal to zero
now you have x+1=0 and x-5=0
finally, solve for x by subtracting 1 and adding 5
now you have your answer x= 5 and -1
Not equal to 2 and 1/10
