2(-322 + x + 1) - 2(4x - 3x + 1)?

-644

Step-by-step explanation:

2(-322 + x + 1) - 2(4x - 3x + 1)

First distribute the 2 and the -2 over the parentheses:

= - 644 + 2x + 2 - 8x + 6x - 2   Now add like terms.

= -8x + 2x + 6x - 644 + 2 - 2

= -8x + 8x - 644

= -644.

-644

Step-by-step explanation: by expanding, 2(-322+x+1) = -642+2x

And -2(4x-3x+1)= -2x-2.

Adding together, we have

-642 +2x -2x-2= -644

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%
