Answer:
B) 102 units
Step-by-step explanation:
The diagonals of a parallelogram bisect each other. This means ...
BE = ED
3 -9x = -8x +14
-11 = x . . . . . . . . . . . . add 9x -14
BE = 3 -9x = 3 -9(-11) = 3 +99
BE = 102 units

Step-by-step explanation:
Answer:
C. 4000
Step-by-step explanation:
let the number of females be : x
number of males be: 10000-x
(10000-x)*105/100 + x*106/100 =10540
10000*105/100 - 105x/100 + 106x/100 =10540
100*105 + x/100 =10540
x/100 =10540-10500
x =40*100
x =4000
Hope this helps!
