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.

Joan waters her plants each day with gallons of water. With a new irrigation system in place, she uses gallons of water each day
vampirchik [111]

Answer:

172\frac{1}{2} gallons

Step-by-step explanation:

Considering she waters her plants with 25 1/2 gallons  i.e 51/2

and with the new system, she does it with 19 3/4 i.e 79/4

taking the difference:

\frac{51}{2} - \frac{70}{4} = \frac{23}{4} gallons per day

For 30 days:

30 x \frac{23}{4} = 172.5 or 172\frac{1}{2} gallons

I’ll give you 30 points if you help
KATRIN_1 [288]

Answer:

2, -2

Step-by-step explanation:

f(x) = 2x + 1

g(x) = x - 3

To find g(f(x)), you need to put f(x) into g(x).

g(f(x)) = (2x + 1) - 3

g(f(x)) = 2x + 1 - 3

g(f(x)) = 2x - 2

Your answer will be 2 and -2.
