Answer:

( x - 4)

Step-by-step explanation:

x² + 2x - 24

From here, you must find the two factors of -24 (the first and third terms' coefficients multiplied together) that add up to 2 (the middle terms coefficient)

( x - 4) ( x + 6)

Other factor of x² + 2x - 24 is (x - 4).

Factors and multiples are two related concepts in math. A factor is a number that divides the given number exactly with 0 as the remainder.

Given expression

x² + 2x - 24 has factor (x + 6)

So, the expression should be divisible by (x + 6)

(x² + 2x - 24)/(x + 6)

It can be written as

(x² + 6x - 4x -24)/(x + 6)

Factoring out common factor

(x (x + 6) - 4 (x + 6))/(x + 6)

factoring out common factor

(x + 6)(x - 4)/(x + 6)

Simplifying

Answer:

104

Step-by-step explanation:

x+37=141

subtract 37 from both sides

 -37=141-37

x= 104

Step-by-step explanation:

x = First number

x + x + 37 = 141 (Because we know that the 2nd number is 37 more than the first, we can just say x + 37.)

2x + 37 = 141 (Combine like terms.)

2x = 104 (Subtract 37 from both sides.)

x = 52 (Divide 2 from both sides.)

Now we know that the first number is 52. Now we just add the 37 to 52 to find the second number.

37 + 52 = 89 = Second number

Proof: 52 + 89 = 141

Answer:

160 ft^2

Step-by-step explanation:

First you have to find the width, then you find the area. To find the width with a percentage we do Part/ Total = %/100  and we cross multiply. We need to find the part so that is the unknown, we will call it 'w' for width

w/20 = 40/100       Now we cross multiply, the x and the 100 and the 20 and 40

w * 100 = 100w

20 * 40 = 800

Now we have 100w = 800      The next step is to divide both sides by 100 so we just have w

100x/100= w

800/100 = 8

w = 8

The width is 8

Now we find the area which is length x width

20 x 8 = 160

So the area is 160 ft^2

Answer:

third option

Step-by-step explanation:

Given f(x) has zeros x = a, x = b, then

the factors are (x - a), (x - b) and the polynomial is the product of the factors.

Complex zeros occur as conjugate pairs, thus

5 + 4i is a zero then 5 - 4i is a zero

The zeros are x = 3, x = - 13, x = 5 + 4i, x = 5 - 4i, thus the factors are

(x - 3), (x - (- 13)), (x - (5 + 4i)), (x - (5 - 4i)), that is

(x - 3), (x + 13), (x - 5 - 4i), (x - 5 + 4i)

= (x - 3), (x + 13), ((x - 5) - 4i), ((x - 5) + 4i)

The polynomial is the product of the factors

f(x) = (x - 3)(x + 13)((x - 5) - 4i)((x - 5) + 4i) ← expand factors in pairs

     = (x² + 10x - 39)((x - 5)² - 16i²) → i² = - 1

     = (x² + 10x - 39)(x² - 10x + 25 + 16)

     = (x² + 10x - 39)(x² - 10x + 41) ← distribute

     = [tex]x^{4}[/tex] - 10x³ + 41x² + 10x³ - 100x² + 410x - 39x² + 390x - 1599 ← collect terms

Answer:

The third option

Step-by-step explanation:

Solution:

Given that,

One of the acute angles in a right triangle has a measure of 34.6°

The sum of the three angles of a triangle is always 180 degrees.

Also, that the measure of a right angle is always 90 degrees

Let "x" be the other acute angle

Therefore,

x + 90 + 34.6 = 180

x + 124.6 = 180

x = 180 - 124.6

x = 55.4

Thus the measure of other acute angle is 55.4 degrees

Answer:

Yes, what the other person said

Step-by-step explanation: basically you subtract 90.0 - 34.6

Answer:

x= 0

Step-by-step explanation:

in order to find the value of x in the 2x - 4(x + 2) = -2X-8

we are going to apply bodmas rule by first opening the bracket

we have,

2x-4x-8 = 2x -8

we proceed to collect the like terms

2x -4x-2x = -8 +8

-4x = 0

divide both sides by -4

-4x/-4 = 0/-4

x= 0

Answer:

B

Step-by-step explanation:

B produces the term 12x that cancels out after subtraction.

In order to eliminate one variable by subtracting, you should multiply the top equation by -3 and the bottom equation by 2. In doing so, this will make the coefficients of y equal and opposite, allowing this variable to be eliminated when the two equations are added together.

The question relates to the method of solving a system of linear equations by subtraction. In order to eliminate one variable when subtracting these equations, we would need to manipulate the equations such that the coefficients of one variable are exact opposites. Hence, the objective is to make the coefficients of y, -2 and -3, opposite each other.

To achieve this, the correct answer is C. Multiply the top equation by -3 and the bottom equation by 2.

By performing these multiplications we'll have:
-12x + 6y = -21.
6x - 6y = 30.
Now, if we add these two equations, we'll be able to eliminate the y variable and can proceed to solve for x.

Answer:

Part a) Alyssa's expectation is equal to $0.33

Part b) Gabriel's expectation is equal to -$0.33

Step-by-step explanation:

we know that

The expected value is the probability of winning multiplied by the value you get when you win, plus the probability of losing multiplied by the value you get when you lose (which is negative as it is a loss).

Part a) Determine​ Alyssa's expectation

we know that

1) If Alyssa rolls a​ 1, 2, or​ 3, Gabriel gives Alyssa ​$4

The probability is 3/6

so

we have

[tex]\frac{3}{6}(4)=\$2[/tex]

2) If Alyssa rolls a​ 4, or​ 5, Gabriel gives Alyssa ​$1

The probability is 2/6

so

we have

[tex]\frac{2}{6}(1)=\$0.33[/tex]

3) if Alyssa rolls a​ 6, she gives Gabriel ​$12

The probability is 1/6

so

we have

[tex]-\frac{1}{6}(12)=-\$2[/tex]  ---> is negative because is a loss

therefore

Alyssa's expectation is equal to

[tex]\$2+\$0.33-\$2=\$0.33[/tex]

Part b) Determine​ Gabriel's expectation

we know that

1) If Alyssa rolls a​ 1, 2, or​ 3, Gabriel gives Alyssa ​$4

Is a loss for Gabriel

The probability is 3/6

so

we have

[tex]-\frac{3}{6}(4)=-\$2[/tex]  ---> is negative because is a loss

2) If Alyssa rolls a​ 4, or​ 5, Gabriel gives Alyssa ​$1

Is a loss for Gabriel

The probability is 2/6

so

we have

[tex]-\frac{2}{6}(1)=-\$0.33[/tex] ---> is negative because is a loss

3) if Alyssa rolls a​ 6, she gives Gabriel ​$12

Is a win for Gabriel

The probability is 1/6

so

we have

[tex]\frac{1}{6}(12)=\$2[/tex]  

therefore

Gabriel's expectation is equal to

[tex]-\$2-\$0.33+\$2=-\$0.33[/tex]

The expected outcomes for both Alyssa and Gabriel from the game are $0. This is calculated using the probabilities of each outcome and their respective gains or losses.

In the game between Alyssa and Gabriel, we are to calculate the expected outcomes for both players. To calculate the expectation, we will weigh the possible outcomes ($4, $1, -$12 for Alyssa and -$4, -$1, $12 for Gabriel) by their probabilities.

The dice has six faces, so the probability for each outcome is determined by the number of corresponding faces divided by six. Let's calculate the expectation for both:

So, both Alyssa and Gabriel have an expected gain of $0 from this game.
