height: 15 ft
area: 285 ft2

a: 57ft
b: 19ft
c. 42ft
d: 38ft

The answer is 19 ft,you divide 285÷15 and that is 19

In both cases, divide by -3 on both sides, but reverse the inequality sign when doing that for the inequality

Step-by-step explanation:

-3x+6=21

-3x+6<21

While solving inequalities , reverse the inequality symbol when we divide or multiply by any negative number

In the first step, we subtract 6 from both sides in both cases

But when we divide by -3 on both sides, but reverse the inequality sign when doing for the inequality.
