We have two sides of length 'w'. They are the vertical sides.
We also have two sides of length '2w+6' which are the horizontal sides.
So we have these four sides
side1 = w
side2 = 2w+6
side3 = w
side4 = 2w+6
Let's add up those four sides to get
Perimeter = (side1)+(side2)+(side3)+(side4)
Perimeter = (w)+(2w+6)+(w)+(2w+6)
Perimeter = w+2w+6+w+2w+6
Perimeter = 6w+12
------------------------
Since the perimeter is given to be 228, and we found the perimeter expression to be 6w+12, this must mean that the two are equal
So, 6w+12 = 228
Let's solve for w
6w+12 = 228
6w+12-12 = 228-12
6w = 216
6w/6 = 216/6
w = 36
------------------------
Now that we know that w = 36, we can find the dimensions of this rectangle
The vertical sides are simply w, so the vertical sides are 36 feet each. I simply replaced w with 36.
The horizontal sides are a bit more complicated. The expression we have is 2w+6 or 2*w+6. Let's replace w with 36 and use PEMDAS to evaluate
2*w+6 = 2*36+6 = 78

Answers are...
Length = 78 feet
Width = 36 feet
(the length is the horizontal component, the width is the vertical)

Standard form of h,k centered circle
(x-h)^2 + (y-k)^2 = r^2
for this circle center, h,k = 2,-13 radius = sqrt (150)= 5 sqrt 6

Answer:
n + (2n + 5) = 50
Step-by-step explanation:
n = Nina’s age
2n = twice Nina’s age
5= Ryan is 5 years older than twice Nina’s age
50 = both their ages combined.
So,
n + (2n + 5) = 50
