Answer:
Step-by-step explanation:
Given that:
the perimeter of the fencing (rectangle) = 200
Let recall that the area equation of a rectangle = L × w
The perimeter now = 2(L + w)
The perimeter = 2L + 2w
∴
200 = 2L +2w
Dividing both sides by 2
100 = L + w
Making Length L the subject; we have:
- L = -100 + w
L = 100 - w
Thus;
A(w) = (100 - w) w
and the domain of the function is (0,100)
Answer: 3
Step-by-step explanation:
Answer:
x=12
Step-by-step explanation:
3(x-1)=2x+9
3x-3=2x+9
3x-2x-3=9
x-3=9
x=9+3
x=12
The answer to the question is d
