Answer:
x³ - x²y
Step-by-step explanation:
x²(x - y) ← multiply each term in the parenthesis by x²
= x³ - x²y

Complimentary angles add up to 90 degrees and supplementary angles add up to 180 degrees...
Complementary angle = 90-52= 38°
Supplementary angle = 180-52= 128°
Using the combination formula, it is found that:
a) 180 different starting lineups can be created.
b) The probability that mary and alice will get on the lineup is .
The order in which the players are chosen is not important, hence the <em>combination formula </em>is used to solve this question.
<h3>What is the combination formula?</h3>
is the number of different combinations of x objects from a set of n elements, given by:
Item a:
The lineup is composed by:
- 2 guards from a set of 5.
- 2 forwards from a set of 4.
- 1 center from a set of 3.
Hence the number of lineups is given by:
Item b:
The number of lineups with Mary and Alice are given as follows:
- 2 guards from a set of 5.
- Mary and 1 other forward from a set of 3.
Hence:
Hence the probability is given by:
The probability that mary and alice will get on the lineup is .
