In the parallelogram shown, ae = p − 8, ce = 2p − 58, and de = p + 15. what is the length of line segment eb?
42 units
50 units
65 units
73 units

The first thing we must do is find the value of p.

For this, we use the following equality:

Substituting values we have:

Clearing the value of p we have:

Then, we look for the length of EB.

We know that:

Substituting values we have:

the length of line segment EB is:

65 units

the 8 in 8,420 is in the thousands place so it's value is 8 thousand.

the 8 in 6,870 is in the hundreds place so it's value is 8 hundred.

divide 8000 by 800 to find the answer:

8000 / 800 = 10

the 8 in 8,420 is 10 times greater than the 8 in 6,870
