Given the point c (18,5) and x (9,-9) find the midpoint of cx

(27/2,-2)

Step-by-step explanation:

Use the midpoint formula.

((x1+x2)/2,(y1+y2)/2).

(18 + 9)/2 = 27/2

(5 - 9)/2 = -2

(27/2,-2)

a. the are of the rectangle is 18.25

b. 18.25 times two is 36.50

rae me : d

dc=6 square root of 3 and ac is 12 square root 3

c and d

step-by-step explanation:

square root of 3/2 = 18/c

cross multiply to get 18*2=√3*c

36/√3 * √3/√3 = c

c= 36*√3/3

c=12√3
