Answer:
area of trapazoid= 1/2 × b× h
so = 1/2×9×15
=1/2×135
=67.5cm
5a.
18/9 = 12/x
18x = 12(9)...cross multiply
18x = 108
x=108/18
x=6
5.5 7
Step-by-step explanation:
All you have to do is subtract 999 from both sides of the equation.
999 + k = 1,721
999 - 999 + k = 1,721 - 999
k = 722
The answer is C.) k = 722
