Answer:
-5x^2 +x
Step-by-step explanation:
x(x-2)-3x(2x-1)
Distribute
x^2 -2x -6x^2 +3x
Combine like terms
-5x^2 +x
Area of smaller frame =1/4×36=9sq.in

Answer:
The question continues ; I take it is defined as a set of five white and one red number how many possible different Powerball tickets can be purchased how many possible different winning Powerball tickets are there
Step-by-step explanation:
he concept of combinatorics ( combination and permutation) is applied her
nPr = n!/(n-r)!
nCr = n!/(n-r)!r!
Hence number of possible different powerball tickets = number of ways of selection
= selecting 5 white ball from a total of 69 and selecting a red ball from a total of 26
= 69C5 x 26C1
using the formula above for combination
= 69!/(69-5)!5! x 26!/(26-1)!1!
= 292, 201, 338 ways
