Which statement must be true?
m2 PKN = mLJKP
m2 PKN = 90 + m2JKP
mZPKN = 180 - MZJKP
m2 PKN = 270 - mJKP
d

4x and 6y

im not sure though

lockers 1, 4, 9, 16, 25, 40, and 49 are open

i ran through it by the other answer is wrong

idk

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."
