A number of squares are connected in a row to form a rectangle. The table shows the relationship between the number of squares, x, and the perimeter, y, of the rectangles they form. Select all the true statements about this relation. Number of Squares, x 1 2 3 4 Perimeter, y 8 12 16 20 The table can be represented by the equation y = 4x + 4. The graph of the function is nonlinear. The relation is a function. The rate of change is NOT constant. The graph of the function is linear.

i think is 3 and 6. this took me 10 min to think.hope to and hope that my answer is brainliest.(follow me )

what is the original number? you forgot to add it.

- "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."
