your friend runs for (x² – 225) seconds at a rate of

per second. how far does your friend run?

(x + 15) / 2

Step-by-step explanation:

Distance = rate × time

d = (x² – 225) / (2x − 30)

d = (x – 15) (x + 15) / (2 (x – 15))

d = (x + 15) / 2

the answer for this question is : 360°

step-by-step explanation:

we have been given a triangle   we need to tell which one of these is a triangle below to map onto itself.

360° rotation is the complete rotation which eventually leads to the same figure which is given.

the correct will be, that is 360° that will cause the triangle below to map onto itself.

1,8,15,22,29,36,43,50
