The length of a rectangle is 5/2 units greater than twice its width. if its width is w, which expression gives the perimeter of the rectangle in terms of w? 1. 2(5/2w) + w 2. 5/2w + w 3. 3w + 10/2 4. 6w + 5

Option 4 is correct

Step-by-step explanation:

Perimeter of a rectangle is given by:

           ....[1]

where w be the width of the rectangle and l be the length of the rectangle.

As per the statement:

length of a rectangle is 5/2 units greater than twice its width.

⇒ units

Substitute this in [1] we get;

Combine like terms;

Using distributive property:

Therefore, the perimeter of the rectangle in terms of w is units

10.416 meters per second

step-by-step explanation:

distance=1 00 meters

time= 9.6 seconds in decimal form or 9 3/5 as a mixed number

average speed= 100/9.6

=10.416 meters per second or 10 52/125 as a mixed number.

step-by-step explanation:

divide, then simplify your answer.

1. make -15.66 ÷   5.8 a fraction. then divide.

2. simplify.  

3. final answer.
