d(d-5)=0
d=0,5
Answer: a
Step-by-step explanation:
-5/8 ; -0.025 ; 33/40 ; 18 ; 18.425
Negative will always be the least and since -5/8 is farther away from 0 it is the least. Then you put down -0.025 since it’s the only other negative available. Next you put 33/40 because it’s less then 1 and one is less then 18. Then you put 18 and lastly you put 18.425
When thinking of this just imagine it in money do I want to be in debt 63 cents or three cents or will I like to have 83 cents or 18 dollars or $18.23

4(3)=12
Answer:
11.6--------------------------------------
Explanation:
See the attached image for a visual reference
The distance from point D to E is 21 units. Point C is the midpoint, so CD is 10.5 units long (21/2 = 10.5)
We have a right triangle ACD. The legs are
AC = 5
CD = 10.5
The hypotenuse is
AD = x
Because AD is another radius of the same circle
Use the pythagorean theorem to find x
a^2 + b^2 = c^2
5^2 + 10.5^2 = x^2
25 + 110.25 = x^2
135.25 = x^2
x^2 = 135.25
x = sqrt(135.25)
x = 11.629703349613
which rounds to
11.6 when rounding to the nearest tenth (one decimal place)
