Answer:
x^2+2x
Step by step explanation:
(2x^2+3x)-(x^2+x)
Remove unnecessary parentheses
2x^2+3x-(x^2+x)
When there is a - in front of an expression in parentheses, change the sign of each term of the expression and remove the parentheses
2x^2+3x-x^2+x
Collect like terms
x^2+3x-x
The number of possible outcomes is 8.
The probability of getting exactly one tail is 3/8.
The probability of getting at most two tails is 3/4.
<h3>What are the probabilities?</h3>
Here is the sample space if 3 coins are tossed: {HHH, HHT, HTH, HTT, THH, THT, TTH, TTT}. There are 8 possible outcomes.
The probability of getting exactly one tail = number of times only one tail is gotten / total number of possible outcomes
3/8.
The probability of getting at most two tails = number of times at most two tails is gotten / total number of possible outcomes = 6/8 = 3/4

$x^2(x+1)+2(x+1)=(x^2+2)(x+1)$
4.7(-5.2)= - 24.44
______________
B= 15
I don’t see an x but if the b is supposed to be the x than the answer is 15
