Rectangle ABCDABCDA, B, C, D is graphed in the coordinate plane. The following are the vertices of the rectangle: A(5, 1),A(5,1),A, left parenthesis, 5, comma, 1, right parenthesis, comma B(7,1)B(7,1)B, left parenthesis, 7, comma, 1, right parenthesis, C(7, 6)C(7,6)C, left parenthesis, 7, comma, 6, right parenthesis, and D(5, 6)D(5,6)D, left parenthesis, 5, comma, 6, right parenthesis.
What is the perimeter of rectangle ABCDABCDA, B, C, D?

answer: a. 74

step-by-step explanation:

it shows divided evenly, so add the 37+37 = 74

- "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."

step-by-step explanation:

the true statements are:

r = set of real numbers

n = set of natural numbers, 1,2,

w = n u{0} = {0,1,}

ummm seems that u didnt post the attachement !
