Answer:

x = 6

Step-by-step explanation:

The first thing you want to do is get x all alone, do this by adding 5 to both sides

2x-5=7

2x=12             now you want to divide both sides by 2 so the x is all alone

x=6

What is the length of the line segment with endpoints (11,−4) and (−12,−4) ?
bija089 [108]

Answer:

Length of the line segment with endpoints (11,−4) and (−12,−4)  is 23 units

Step-by-step explanation:

Given:

Endpoints are (11,−4) and (−12,−4)

To Find:

The length of the line = ?

Solution:

The length of the line can be found by using the distance formula

\sqrt{(x_2-x_1)^2 +(y_2 - y_1)^2

Here

x_1= 11

x_2= -12

y_1= -4

y_2= -4

Substituting the values

Length of the line

=>\sqrt{((-12)- 11)^2 +((-4) - (-4))^2

=>\sqrt{(-12- 11)^2 +(-4+4)^2

=>\sqrt{(-23)^2 +(0)^2

=>\sqrt{529}

=>23

Factor x2 + 16 completely.
Dmitry_Shevchenko [17]
<h3>Answer:</h3>

Prime

<h3>Solution:</h3>
  • Let's factor this expression.
  • x^2+16
  • The expression is prime.
  • Let's see why all the other options are wrong.
  • Option A) (x+4)(x+4)
  • x*x
  • x*4
  • 4*x
  • 4*4
  • This makes x^2+8x+16, not x^2+16.

Hope it helps.
