A rectangle has an area of 99 square in. What is the length of the long side?

The longer length is either 99, 33 or 11 inches

Step-by-step explanation:

Given

Required

The length of the longer side

Area of a rectangle is:

List out all possible products that give 99 [Assume the dimension are whole numbers]

List out the longer factors

Hence, the longer length is either 99, 33 or 11 inches

34

step-by-step explanation:

- "runner b is moving at a slower rate."

- "the graphs shown are graphs of distance(km) against time(min).

the slopes of this graphs are are given by:

slope = (change in y)/(change in x)

= (change in distance)/(change in time)

this is the formula for finding the speed. so, the slope of these graphs represent the speed of the runner.

taking each division in the graph to represent 1 on both axis:

runner a ⇒ speed = (2-0)/(1-0)

= 2/1

= 2 km/min

runner b ⇒ speed = (3-0)/(3-0)

= 3/3

= 1 km/min

this shows that   runner b is moving at a slower rate."
