Answer:

B (x^2 +4x -2) + (x^2 -2x +4)= 2x^2 +2x +2

Step-by-step explanation:

The blue are positive and the red are negative

The top line is x^2 +4x -2

The second line is x^2 -2x +4

Adding together  

 x^2 +4x -2 + x^2 -2x +4= 2x^2 +2x +2

Answer:

<em>Part 1 : Equation: ( 3x - 9 ) + 30 + 24 = 180,</em>

<em>Part 2 : Value of x ⇒ 45°,</em>

<em>Part 3 : Measure of Angle U ⇒ 126°</em>

Step-by-step explanation:

~ Part 1 ~

We know that ∑ of angles in a triangle is 180;

m∠ U + m∠ V + m∠ W = 180°,

<em>Equation: ( 3x - 9 ) + 30 + 24 = 180</em>

~ Part 2 ~

Now let us simplify the equation above to solve for x;

3x - 9 + 30 + 24 = 180,

3x - 9 = 126,

3x = 135,

x = 45 degrees ( ° ) ⇒

<em>Value of x ⇒ 45°</em>

~ Part 3 ~

If it is known that m∠ U ⇒ 3x - 9;

m∠ U = 3 * ( 45 ) - 9,

m∠ U = 135 - 9,

m∠ U = 126 degrees ( ° ) ⇒

<em>Measure of Angle U ⇒ 126°</em>

1) The sum of the two numbers is even either the two numbers are even or the two numbers are odd.

2) The probability that the two numbers are even is the product of the probabilities for each event:

- Probability that the first number is even: 10 / 20 = 0.5

- Probability that the second number is even: 10 / 20 = 0.5

- Probability that the two numbers are even: 0.5*0.5 = 0.25

3) The probability that the two numbers are odd is the product of the probabilities for each event:

- Probability that the first number is 0dd: 10/20 = 0.5

- Probability that the second number is odd: 10/20 = 0.5

- Probability that both numbers is odd = 0.5*0.5 = 0.25

4) Probability tha the sum is eve: 0.25 + 0.25 = 0.5

Answer: 0.5.

And it is reasonable, half of times the sum is even and half the sum is odd.
