The owner of an office building is expanding the length and width of a parking lot by the same amount. The lot currently measure
nasty-shy [4]

Present area = 120 * 80 = 9600 ft^2 so the new area will be 9600 + 4400 = 14000

So if increase in length = x we have

(x + 120)(x + 80) = 14,000

x^2 + 200x + 9600 - 14000 = 0

x^2 + 200x - 4400 = 0

x = 20 feet answer

Rina8888 [55]

ANSWER

The linear equation is: y = 80x + 65

Te cost for 40 football jerseys: $3265

EXPLANATION

Let 'x' be the number of jerseys and 'y' the cost of x jerseys.

Each jersey costs $80, so the cost of x jerseys is 80x. There's also an extra fee for procesing of $65, which is the same no matter how many jerseys they buy.

Therefore, the cost 'y' of x jerseys is:

y=80x+65

Now we want to know the cost of 40 football jerseys, so we just have to replace x by 40 and solve:

\begin{gathered} y=80\cdot40+65 \\ y=3200+65 \\ y=3265 \end{gathered}

Answer:

  17.74

Step-by-step explanation:

The fraction is easily converted to one with a denominator of 100 (a power of 10):

Then the number of interest is ...

  17 37/50 = 17 74/100 = 17.74
