Find the solutions to the equation below check all that apply 4x^2+4x+1=0 a. x=-1/2 b. x=1/2 c. x=3 d. x=2 e. x=3/2 f. x=-2

A.

X= -1/2  

I hope works for you tho:)

314.16 m

Step-by-step explanation:

The distance across the track is 100 metres. This means that the diameter is 100 m.

The track is circular, so, we need the circumference.

The circumference of a circle is given as:

C = πD

where D = diameter

Therefore, the circumference of the track is:

C = π * 100 = 314.16 m

She walked a distance of 314.16 m
