Two vertices of a polygon are ( 7, -18) and (7, 18). What is the length of this side of the polygon?

Scilla [17]

Because the two vertices have the same x-coordinate, the side is a vertical line. It starts vertically from -18 to 18

the length = 18 - (-18)
the length = 18 + 18
the length = 36

The length of the side is 36 unit

Deborah bought a computer for 25% off the list price. If the list price is $2,428, how much did Deborah spend? A. $607 B. $1,821

Softa [21]

Answer:

Option A, $\$607$

Step-by-step explanation:

Given: Deborah bought a computer for $25\%$ off the list price.

The list price is $\$2,428$ .

To find: The amount Deborah spent on the computer.

Solution: We have,

List price of the computer $=\$2,428$ .

Deborah bought the computer for $25\%$ off the list price.

The amount Deborah spent on the computer $=25\% \times 2,428$

$=\frac{25}{100}\times2428=\frac{2428}{4} =\$ 607$ .

So, Deborah spent $\$607$ on the computer.

Hence, option A is correct.
