Assuming that these are seperate equations:

Problem 1:

1) Use the sum-product pattern.

x² - 5x - 6

x² + x - 6x - 6

2) Common factor from the two pairs.

x² + x - 6x - 6

x (x + 1) - 6 (x + 1)

3) Rewrite in factored form.

x (x + 1) - 6 (x + 1)

(x - 6) (x + 1)  ----> Answer

Problem 2:

1) Use the sum-product pattern.

x² + 3x - 40

x² + 8x - 5x - 40

2) Common factor from the two pairs.

x² + 8x - 5x - 40

x (x + 8) - 5 (x + 8)

3) Rewrite in factored form.

x (x + 8) - 5 (x + 8)

(x - 5) (x + 8) ----> Answer

Problem 3:

1) Use the sum-product pattern.

x² - 7x - 30

x² + 3x - 10x - 30

2) Common factor from the two pairs.

x² + 3x - 10x - 30

x (x + 3) - 10 (x + 3)

3) Rewrite in factored form.

x (x + 3) - 10 (x + 3)

(x - 10) (x + 3) ----> Answer

Step-by-step explanation:

Answer:

56 degrees

Step-by-step explanation:

The total amount of degrees in a triangle is 180: all three angles add up to 180. We can set up an equation to solve this.

40 + 2x + 3x = 180

Let's add like terms:

40 + 5x = 180

Subtract 40 on both sides:

5x = 140

Divide by 5 on both sides to solve for x:

x = 28

Angle A is equal to 2x. Plug in 28 for x. 2*28 = 56. Therefore, Angle A is 56 degrees.

Answer:

∠ A = 56°

Step-by-step explanation:

the sum of the 3 angles in a triangle = 180°

sum the 3 angles and equate to 180

2x + 3x + 40 = 180

5x + 40 = 180 ( subtract 40 from both sides )

5x = 140 ( divide both sides by 5 )

x = 28

then

∠ A = 2x = 2(28) = 56°

The probability of getting red marble from the consider withdrawal of a marble is 0.107 approximately.

Suppose that there are finite elementary events in the sample space of the considered experiment, and all are equally likely.

Then, suppose we want to find the probability of an event E.

Then, its probability is given as

[tex]P(E) = \dfrac{\text{Number of favorable cases}}{\text{Number of total cases}} = \dfrac{n(E)}{n(S)}[/tex]

where favorable cases are those elementary events who belong to E, and total cases are the size of the sample space.

Given that:

The bag contains:

Since he draws one marbel, thus, only one colored marble would come out.

Let we suppose we've to find P(red marble coming out).

Then, if we take:

E = event of Rafael drawing a red marble,

then E can be done in 6 ways as there are 6 red marbles to choose from.

Also, withdrawal of 1 marble (of any color) can be done in (5+6+45 = 56) 56 ways.

Thus, we get:

[tex]P(E) = P(\text{Choosing a red marble}) = \dfrac{6}{56} = \dfrac{3}{28} \approx 0.107[/tex]

Thus, the probability of getting red marble from the consider withdrawal of a marble is 0.107 approximately.

Answer:

129

Step-by-step explanation:

The easiest thing to do would be an equation.

Since the value is decreasing by 6 each time you have -6x

-6x+?=?

Next thing you do, to get the y-intercept, would be to add 6 to the 309, which is the first term in order to get the zeroth term. This would make 315 the y-intercept

-6x+315=?

To solve for the 31st term, plug in 31 for x to get 129

As per the law of conservation of energy:

C. The reaction system absorbs 22 kJ of energy from the surroundings

This law of energy states that the energy remains conserved its neither created nor destroyed. It remains conserved throughout the reaction.

when an amount of heat gets absorbed during the reaction from the surroundings this type of reaction is known as an endothermic reaction.

So, for fulfilling law of conservation, same amount of energy must be asborbed.
