The area of a rectangle is 28 square meters. The length is 7 meters.
What is the width of the rectangle?

The width is 4 meters

Step-by-step explanation:

The area of a rectangle is

A = l*w

We know the area and the length

28 = 7*w

Divide each side by 7

28/7 = 7w/7

4 =w

in the attachment.   i didn't see your choices.   the word which means there is choices.

step-by-step explanation:

(x,y)

x tells you how much left or right you go from the origin

y tells you how much down or up you go from the origin

so for example (-3,2), you go left 3 and up twice. i denoted which of the ordered pairs is which in my graph.

c.

step-by-step explanation:

she should of added 9^2 and 12^2. that is because it is a^2+b^2=c^2. c^2 is the hypotenuse and should always be bigger than the other two numbers. which is why she should of added 9 squared and 12 squared together instead of 15 squared.
