I don’t get this, i already tried but i can’t get it right

23.82

Step-by-step explanation:

1) if the coordinates are: A(-5;4), B(0;3), C(4;-1) and D(4;-5), then it is possible to calculate the sides of the given quadretarial;

2) AB=sqrt(26)≈5.1; BC=sqrt(32)≈5.66; CD=4; AD=sqrt(82)≈9.06;

3) the required perimeter is: AB+BC+CD+AD=5.1+5.66+4+9.06=23.82 (units)

76%

step-by-step explanation:

24% are dogs and the remaining is 76% because 100-24=76

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
