which equation can be used to solve for x in the following diagram?

Answer:

The correct choice is option a.  (2x+5)(2x−5)

Answer:

Option a. (2x+5)(2x-5)

Step-by-step explanation:

4x2 - 25

Furthermore, this is the difference of squares formula we will use to factor 4x^2-25:

a2 - b2 = (a + b) • (a − b)

As you can see, our problem does not look like the left side of the formula, so first we have to convert our problem to match the left side like so:

4x2 - 25 = (2x)2 - 52

Now that it matches, we can simply plug in 2x for a and 5 for b into the formula to get the factors of 4x^2-25:

(2x + 5) • (2x − 5)

Answer: 14x+6

Step-by-step explanation:

by using distribution from the ”2” outside the parenthesis, you simply do

2x7= 14 (add the variable x) so 14x

then you do 2x3= 6

Answer:

The guitar's volume was amplified, but it was hard to hear the notes since it was so loud.

What word or phrase is a signal word that a context clue might be nearby to help determine the meaning of "amplified"?

Step-by-step explanation:

Step-by-step explanation:

[tex]4x - 2 = 18x + 5[/tex]

Collect like terms and simplify

[tex] - 2 - 5 = 18x - 4x \\ - 7 = 14x[/tex]

Divide both sides of the equation by 14

[tex] \frac{ - 7}{14} = \frac{14x}{14} \\ - \frac{1}{2} = x[/tex]

Answer:

x = -1/2

Step-by-step explanation:

4x-2=18x+5

-2-5=18x-4x

-7=14x

-7/14=14/14x

-1/2=x

Answer:

Step-by-step explanation:

M=189

N = 48

A = M*N

A = 189 * 48

A = 9072

Answer: D. n > -4

Step-by-step explanation:

Given

-3n < 12

Divide both sides by -3. REMEMBER to change the [>,<] signs when multiplying or dividing a negative term

-3n / -3 > 12 / -3

n > -4

Hope this helps!! :)

Please let me know if you have any questions

Hey there! I'm happy to help!

Inequalities are solved like normal equations with a few extra rules.

So, we could simply divide both sides by -3 to get our answer, but n<-4 would actually be incorrect. With inequalities, dividing by a negative number means you have to flip the inequality sign. This is because you turn the other side negative so you need to adjust the inequality sign to match it.

So, our final answer will actually be n>-4.

Have a wonderful day and keep on learning! :D

Answer:

-2

BRAINLIEST, PLEASE!

Step-by-step explanation:

5 - 3(2a + 1) = -4a + 10

5 - 6a - 3 = -4a + 10

2 - 6a = -4a + 10

-2a = 8

a = -4

-4 + 2 = -2

Answer:

a+2 = -4+2 = -2

Step-by-step explanation:

5-3(2a+1)=-4a+10

Distribute

5 - 6a -3 = -4a +10

Combine like terms

-6a +2 = -4a +10

Add 6a to each side

-6a+2 +6a = -4a+6a +10

2 = 2a+10

Subtract 10 from each side

2-10 =2a+10-10

-8 = 2a

Divide by 2

-8/2 =2a/2

-4=a

Answer:

  m = (5x -6)/(43y -4)

Step-by-step explanation:

Subtract 4m+6 to separate m-terms from other terms.

  5x +4m -(4m +6) = 43my +6 -(4m +6)

  5x -6 = 43my -4m

  5x -6 = m(43y -4) . . . . factor out m

 (5x -6)/(43y -4) = m . . . . divide by the coefficient of m
