The length of a rectangle is 9 inches and its perimeter is 48 inches. What is the width of the rectangle?

lana [24]

A.) Equation of Perimeter of a rectangle (P) = 2(l + w)

48 = 2(9 + x)

B.) Solving: 48 = 2(9 + x)

48 = 18 + 2x

2x = 48 - 18

x = 30/2

x = 15

In short, Width would be: 15 inches

Find the distance between the points (-6,-2), (2,7)

Readme [11.4K]

Answer:

$d=12.0416$

Step-by-step explanation:

Distance Formula: $d=\sqrt{(x_2-x_1)^2+(y_2-y_1)^2}$

Simply plug in your 2 coordinates into the distance formula to find distance <em>d</em>:

$d=\sqrt{(2-(-6))^2+(7-(-2))^2}$

$d=\sqrt{(2+6)^2+(7+2)^2}$

$d=\sqrt{(8)^2+(9)^2}$

$d=\sqrt{64+81}$

$d=\sqrt{145}$

$d=12.0416$
