Sara is building a fence that will be 7 miles long when it is completed. Sara has finished building 2/3 of the fence. What is the length of fence (in miles) that Sara still needs to build to complete the fence?

7/3 ft

Step-by-step explanation:

Given data

Lenght of fence= 7 miles

Amount completed= 2/3 of the total length

let us find the amount completed already = 2/3*7= 14/3 miles

Hence the length of fence remaining for completion is

=7- 14/3

=21-14/3

=7/3

Hence the amount in length undon is 7/3 ft

step-by-step explanation:

quartic functions has x = –1 and x = –2 as its only two real zeroes:

f(x) = a(x+2)(x+1)   a: real number
