Mark and Zoe are hiking a trail. Mark starts before Zoe. The expression 2t + 100 represents how far, in meters, Mark has hiked t seconds after Zoe starts, and 2t represents how far Zoe has hiked t seconds after starting. Is there a time during the hike when Mark and Zoe have hiked the same distance? Explain.

No

Step-by-step explanation:

The distance hiked of Mark is represented by 2*t + 100

and the distance hiked of Zoe is represented by 2*t

here, you can see that the slope of both equations is equal, this means that in the same lapse of time, Zoe and Mark displace the same amount, but because Mark started earlier, he has a y-intercept bigger than zero, so for every value of t, the distance that Mark hiked will be higher than the one of Zoe.

We can represent this by:

2*t + 100 > 2*t

100 > 0

So the distance hiked by Mark is always bigger than the one of Zoe

D) 32

Step-by-step explanation:

The volume of a cube is:

v=s³

512=s³

Take the cube root of both sides

s=8

To find the perimeter of a square,

p=4s

p=4(8)

p=32

So, D is your answer! Hope this helped!
