Elissa wants to set up a rectangular dog run in her backyard. she has 30 feet of fencing to work with and wants to use it all. if the dog run is to be x feet long, express the area of the dog run as a function of x.

a. a(x)=14x-x^2
b. a(x)=15x-x^2
c. a(x)=17x^2-x
d. a(x)=16x-x^2

c

step-by-step explanation:

it isn't d, because the interquartile range is from 27-57. and the interquartile range is basically half the data, it's pretty obvious.

it isn't b, because like i said earlier, the interquartile range is from 27-57. 57-27 is 30. the real range has to be longer

not a either. although it looks like it, 3/4 of the data is not greater than 27. but if c is wrong than this should be correct

the correct answer is c, because 13 is the point in which the plot starts

step-by-step explanation:

answer: 12   they all have at least 28 days

step-by-step explanation: haha

answer: the angel abc is 30°,and the abc is a triangle where the angel bac is 90°

so ac is the half of 24=12ft,and from the pythagorean theorem we find ba

ba=√bc^2-ac^2=√576-144=√432=12√3ft

so bac is 12+12√3=12(1+√3)ft
