the length of a rectangle is 4 cm more than the width and the perimeter is at least 48cm. what are the smallest possible dimensi

wel

X=length
x+4=width
$2(x+4)+2x=48$
$2x+8+2x=48$
$4x=40$
$x=10$
It means that length will be equal 10 and width 14 :)
so dimensions of this rectangle is 10x14 :)

Mrs. Brown drove 105 miles in 2.5 hours. What was Mrs. Browns speed in miles per hour?

fiasKO [112]

Answer:

42mph.

Step-by-step explanation:

We know that the formula for miles per hour is.

r = d/t

R is our rate or miles per hour.

D is our distance.

T is our time.

In this case our distance is 105 miles.

And our times is 2.5 hours.

Therefore if we substitute them into our formula:

105mi ÷ 2.5hrs = 42mph

Hope this helped!
