2. Find the value of x.
My name is Ann [436]

Answer:

x = 6

Step-by-step explanation:

3(x + 2) =24

Divide each side by 3

3/3(x+2) = 24/3

x+2 = 8

Subtract 2 from each side

x+2-2 = 8-2

x = 6

Rewrite the expression in factored form: x^2+12x+27
max2010maxim [7]

Answer:

c. (x+3)(x+9)

Step-by-step explanation:

x^2+12x+27

The middle number is 12 and the last number is 27.

We need two numbers that...

Add together to get 12

Multiply together to get 27

Try 3 and 9:

3+9 = 12

3*9 = 27

Fill in the blanks in

(x+_)(x+_)

with 3 and 9 to get...

(x+3)(x+9)

Sloan [31]

Answer:

Sum of \frac{7x}{x^2-4} and \frac{2}{x+2} is \mathbf{\frac{9x-4}{x^2-4}}

Option B is correct answer.

Step-by-step explanation:

We need to find sum of \frac{7x}{x^2-4} and \frac{2}{x+2}

Finding sum of  \frac{7}{x^2-4} and \frac{2}{x+2}:

\frac{7x}{x^2-4}+\frac{2}{x+2}

We know that x^2-4 =(x+2)(x-2)

Replacing x^2-4

\frac{7x}{(x+2)(x-2)}+\frac{2}{x+2}

Now, taking LCM of (x+2)(x-2) and (x+2) we get (x+2)(x-2)

=\frac{7x+2(x-2)}{(x+2)(x-2)}\\=\frac{7x+2x-4}{(x+2)(x-2)}\\=\frac{9x-4}{(x+2)(x-2)}\\=\frac{9x-4}{x^2-4}

So, Sum of \frac{7x}{x^2-4} and \frac{2}{x+2} is \mathbf{\frac{9x-4}{x^2-4}}

Option B is correct answer.

Drag the tiles to the correct boxes to complete the pairs. Solve the inequalities for x, and match each solution to its number l
svetlana [45]

in the figure, the first number line goes with x \leq5

the second number line goes with x \geq 5

the third number line goes with x > 5

the fourth number line goes with x < 5

Two less than 3/2 of a number x is  no more than 5/2 is shown as:

3/2 x- 2 \leq 5 1/2

3/2 x \leq 11/2 + 2

3/2 x \leq 15/2

3x \leq 15

x \leq 5

The sum of two times a number (x) and -2 is at least 8 is shown as :

2x+(-2) \geq 8

2x - 2 \geq 8

2x \geq 8+2

2x \geq 10

x \geq 5

Seven subtracted from 4 times a number (x) is more than 13 is shown as

4x -7 > 13

4x > 13+7

4x > 20

x > 20 ÷ 4

x > 5

Four added to 3 times a number (x) is less than 19 is shown as

3x + 4 < 19

3x < 19-4

3x < 15

x < 15 ÷ 3

x< 5

Please help! I'll give 30
Softa [21]

Answer:

B is correct

Step-by-step explanation:

The person is mentioned is Phil. His amount of money and number of miles are proportionally related (Clark's amount of money and number of miles are not proportionally related due to initial donation)

For Phil, y = ax is his model.

Look into the graph, we can see there is a point where y = 30 and x = 4.

Then rate = 30/4 = 7.5
