The area of the square = (2x + 3)^2 = 4x2 + 12x + 9.
I got V = X to the power of 5
Answer: 4.5 minutes.
Step-by-step explanation:
1. You have the following information given in the problem above:
- Erica runs
in a minute.
- The school is
away from her home.
2. Therefore, to solve the exercise you must multiply
by 1 minute and divide this by
, as following:

3. Therefore, the result is 4.5 minutes.
Answer:
Length = 120 ft
Total cost = 1500$
Step-by-step explanation:
First, to find the length of the backyard we reverse the formula (A = l * w) and divide 10,800 by 90.
10,800 ft^2 / 90 ft = 120 ft.
we can check this by plugging the length of 120 ft into the formula:
120 ft * 90 ft = 10,800 ft^2.
Next, to find the cost of the single length of fence we multiply our length (120 ft) by the cost ($12.50):
120 * 12.50 = $1500
We know that Ava is paying $2 dollars per week so if L is the money that she owes and t is the number of weeks, and I is the initial debt so we can write an equation like:

Now we can replace the info we have to find the value of I so:

and we solve for I

So the final equation will be:
