The value of x is 3, while the length of the rectangle is 30 units and the width is 24 units.
<h3>How to determine the dimensions?</h3>
The given parameters are:
Base = 5(x+3)
Height = 2(x+9)
Perimeter = 108
The perimeter of a rectangle is
P = 2 *(Base + Height)
So, we have:
2 *(5(x + 3) + 2(x + 9)) = 108
Divide both sides by 2
5(x + 3) + 2(x + 9) = 54
Open the brackets
5x + 15 + 2x + 18 = 54
Evaluate the like terms
7x = 21
Divide by 7
x = 3
Substitute x = 3 in Base = 5(x+3) and Height = 2(x+9)
Base = 5(3+3) = 30
Height = 2(3+9) = 24
Hence, the value of x is 3, while the length of the rectangle is 30 units and the width is 24 units.

Answer:
The height of the building is 730 feet.
Step-by-step explanation:
370 x 12 = 4,440 inches
4,440 ÷ 18.5 = 240 inches
240 x 36.5 = 8,760 inches = 730 feet
Answer: There are 20 boys

So I had to reread this about 3 times before it finally clicked, I've never done a problem like this before. An ordered pair is organized like so: (x-coordinate, y-coordinate) Meaning x=4 and y=6. If x=hot dogs and y=drinks then this means that Ben purchased 4 hot dogs and 6 drinks at the game.
Hope this helps!! (:
I found that Joe has 28 red pepper plants and 8 green pepper plants.
to find this, I first set up a proportion:
7/2 = (20+x)/x
then you cross multiply giving you:
7x = 40 + 2x
Subtract 2x from both sides:
5x = 40
solve for x:
x = 8 (which is the amount of green pepper plants)
to find how many red pepper plants he has, plug in x for (20 + x) giving you 28 red pepper plants
Hope I helped :)
