2x + 3 = 9 Move all terms not containing x to the right side of the equation.

2x = 6 Divide each term by 2 and simplify.

x=3

You make 2x+3 equal 19 so like this 2x+3=19 then you subtract 3 over to 19 and that is 2x=16 then you divide 16 by 2 and that is 8 so x=8

Evaluate P(3,3) help please

scZoUnD [109]

$P(n,k)$ where $n=k$ is equal to $n!$

So, $P(3,3)=3!=6$

Generally, $P(n,k)=\dfrac{n!}{(n-k)!}$

A and B are independent events. P(S) = 0.40 and P(B) = 0.30. What is P(A and B)

n200080 [17]

The value of the probability P(A and B) is 0.12

<h3>How to determine the probability?</h3>

The given parameters are

P(A) = 0.40

P(B) = 0.30

Given that the events are independent events;, we have:

P(A and B) = P(A) * P(B)

So, we have:

P(A and B) = 0.40 * 0.30

Evaluate

P(A and B) = 0.12

Hence, the value of the probability P(A and B) is 0.12

What is the solution of StartRoot x + 2 EndRoot minus 15 = negative 3?

Brilliant_brown [7]

Answer:

x = 142

Step-by-step explanation:

The problem;

$\sqrt{x+2} - 15 = -3$

Inverse operations;

$\sqrt{x+2} -15 = -3\\ +15 +15\\\\\\\\\sqrt{x+2} = 12\\\\$

Now undo the square, by squaring both sides;

$\sqrt{x+2} = 12\\.^{2} \\\\\\ \\x+2 = 144$

Inverse oeprations;

x + 2 = 144

-2 -2

x = 142
