Answer:
The area is 15 feet
Step-by-step explanation:
So you are going to need two different equations-
l = w(3)
2l + 2w = 40
Insert the first equation into the second-
2(3w) + 2w = 40
Simplify this equation-
6w + 2w = 40
8w = 40
Divide both sides by 5
w = 5
Solve first equation
l = 5(3)
l = 15
Then find the area-
5 x 15 = 75
Answer: -5, -7, and -9
Step-by-step explanation:
checking the pattern they are subtracting by two by the next term, so subtracting 2 from -3 would be -5 and so on.
I think this is a function..
