A. 3.3 units
B. 7.8 units
C. 5.2 units
D. 3.6 units

PLEASE HELP!!!!!

Answer 1

7.8 Units.

Explanation: I just took the test.

Answer 2

We have that
A(-4,-4) B(-2,5)  C(2,1)  D(2,-4)

step  1
find the distance AC with the formula 
d=√[(y2-y1)²+(x2-x1)²]------> dAC=√[(1+4)²+(2+4)²]----> dAC=√61 units
dAC=√61-----> dAC=7.8 units

the answer is
the option
B. 7.8 units
