Can i get some been trying to figure this question on but don’t seem to get it.

Step-by-step explanation:

If you square the binomial (x -a), you get ...

  (x -a)² = x² -2ax +a²

Comparing this to your equation, you find that ...

  -2a = -5/3 . . . . . . the x-coefficient

  a = (1/2)(5/3) = 5/6

So, the number in the right box is 5/6, and the number in the left box is its square, (5/6)² = 25/36.

Filling these in, the equation reads:

  x² -5/3x +25/36 = (x -5/6)²

__

That is, the constant in the squared binomial is half the x-coefficient.

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."
