8x-38

Step-by-step explanation:

distribute:

(3)(x)+(3)(-6)+(5)(x)+(5)(4)

3x+-18+5x+-20

Combine like terms:

3x+-18+5x+-20

(3x+5x)+(-18+-20)

8x+-38

Hope this helps

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%

logv3(x+2)=1

rewrite in exponential form:

logb(x) = y is equal to b^y =x

b = 3, y = 1

now solve for x:

3^1 = x+2)

x = 3-2

x = 1

see the picture for the graph.
