Carla and jonah are working together to determine if quadrilateral CDEF with coordinates c(2,3), D(1,2) E(4,1) and F(5,3) has a right angle. Carla's sets up the following equations: mcd=2-3/1-2
Mde=1-2/4-1 Jonah sets up the following equations: mcd= 2-3/1-2 Mef=3-1/5-4
Who is on track to get the correct answer and why?

walter needs to make at least 5 more cookies but no more than 40. 5 ≥ x ≥ 40;

step-by-step explanation:

walter has to make a minimum of 20 cookies. he already has 15 cookies made, so he must make 5 more to meet the minimum.

the maximum amount of cookies he can make is 55. he already has 15, so he has to make no more than 40 more cookies to meet the maximum.
