On considère l’expression A = ( 2x – 1 )² + ( 2x – 1 ) ( x + 4 ).
1. Développer et réduire A.

A = 6x^2+3x-3

Step-by-step explanation:

expand the first term:

multiply the second terms:

simplify by combining like terms:

oui, je parle un peu de francais. <<Développer>> = expand et <<réduire>> = simplify.  

darn right!

0.16 or 16%

step-by-step explanation:

lets take a coin for example.

if you toss it twice, it has a 1/4 chance of landing on heads both times because 1/2 * 1/2 is 1/4.

with the cards, the chance of picking dog is 0.4. having two people pick one is like picking a card twice in a row. so 0.4 * 0.4 is 0.16, or 16%
