Answer:
Perimeter = 180
Area = 1080
Step-by-step explanation:
Perimeter is length of all sides added together. 30+78+72 = 180

In that statement of a function, 'a', 'b', and 'c' all represent
plain old ordinary constant numbers.
Answer:
height
Step-by-step explanation:
you can just look these questions up
-2 / 5y = 4
Multiply both sides by 5y:
-2/ 5y * 5y = 4 * 5y
refine: -2 = 20 y
Switch sides:
20 y = - 2
Divide both sides by 20
20 y / 20 = - 2 / 20
y = -1/10
hope this helps!
