& Cassandra took 87 pads from Louie. Louie now only has 15 left. Mr. Flynn doesn't like ipads. How many did Louie have BEFORE Cassandra took some?

9514 1404 393

  102

Step-by-step explanation:

87 more than 15 is ...

  15 +87 = 102

Louie had 102 iPads before Cassandra tool some.

check the picture below.

well, the angle at the vertex d is clearly not a right-angle, let's check for the one at the vertex f which does look like,   however if it's indeed, that means ef is perpendicular to df, in which case their slopes will be negative reciprocal of each other.

so the negative reciprocal of the slope of ef is 1, however the slope of df is not 1, is 1/2, so nope, they're not perpendicular lines.

{3 + i, 3 - i, 3, -1}
