Answer: its width is 7cm

Step-by-step explanation:

The perimeter of a rectangle is the sum of twice its length plus twice its width.

perimeter = 2·length + 2·width

34centimeters = 2·10cm + 2·width

width = (34cm -20cm)/2 = 14cm/2 = 7cm

Answer: its width is 7cm

HELP ASAP Linear Equations

Scilla [17]

Answer:

4th choice: I and IV only

Step-by-step explanation:

Change the form of the given equation to standard form.

y = -2/3 x + 2

3y = -2x + 6

2x + 3y = 6

Now compare this equation with the 4 choices.

Any equation that has the same x- and y-terms but a different constant term is parallel.

I. is parallel.

II. and III. are not parallel.

Look at IV.:

4x + 6y = 3

Divide both sides by 2:

2x + 3y = 3/2

IV. is also parallel.

Answer: 4th choice: I and IV only
