Answer:
2x³ + 12x² + 10x - 24
Step-by-step explanation:
(2x² + 6x - 8)(x + 3) Distribute
2x³ + 6x² + 6x² + 18x - 8x - 24 Combine like terms
2x³ + 12x² + 10x - 24 This expression is in standard form

Answer:
(a)
(b)
Step-by-step explanation:
See attachment for initial punnet square
Solving (a): Complete the square
Initially, we have:
To complete the square, we simply write the letter at the column and the letter at the row in each cell;
So, we have:
Solving (b): Percentage of each
From the question, we understand that W are dominant to w.
So:
From (a) above
So, the percentage of each is:

A. true, P does two complete rotations returning to it's original spot. 720° / 360° = 2
B. false, reflecting across a line will move P.
C. true, moving up 2 then down 2 returns P to it's original position.
D. true, if P is on the line of reflection it remains there.
E. false, P does only 4.5 rotations moving to different coordinates. 1620° / 360° = 4.5
<span> the 1st letter can be put into any of the 5 envelopes,
the 2nd letter in any of the 4 r3maing envelopes, & so on,
giving a total of 5*4*3*2*1 = 120 ways,
while there is just 1 way to insert all letters into correct envelopes
Pr = 1/120</span>
