ANSWER: x = -4

Explanation: if you use distributive property with the parentheses it leaves you with 2x + 12 which the equation will then change to 2x+12 = -5x-16 you then subtract the 12 to the -16..

after that the equation would change to 2x = -5x-28 then now what you would do it add the 5x to the 2x and would get 7x...

after that the equation would then change to 7x = -28 you would then divide by 7 and that would bring up the answer of -4.

Hope this helps

Answer: $x=-4$

Simplify both sides of the equation

$(2)(x)+(2)(6)=-5x+-16(Distribute)\\2x+12=-5x+-16$

Add 5x to both sides

$2x+12+5x=-5x-16+5x\\7x+12=-16$

Subtract 12 from both sides

$7x+12-12=-16-12\\7x=-28$

Divide both sides by 7

$7x/7=-28/7\\x=-4$

Answer:

2,-1.5

Step-by-step explanation:

To find the midpoint of a line segment, take the average of the x coordinates and y coordinates of the two points that make it up.

$\frac{2+2}{2} ,\frac{4+(-7)}{2}$

= $\frac{4}{2} , \frac{-3}{2}$ $\frac{4}{2} , \frac{-3}{2}$

=2,-1.5

Jorge randomly selects a digit from 0 to 9. What is the probability that the digit he selects is a prime number?

zloy xaker [14]

Step-by-step explanation:

{0,1,2,3,4,5,6,7,8,9}--set of numbers from 0 to 9

{2,3,5,7}---set of prime numbers from 0 tp 9

there are 10 numbers in the first set and 4 numbers in the second set.

4/9 is the probability that the digit he selects is a prime number

Hope that helps :)

Find the perimeter of pentagon STUVW WITH VERTICES S(0,0) T(3,-2) U(2,-5) V(-2,-5) W(-3,-2)

andrew11 [14]

Use the distance formula.

$\sqrt{( x_{2} - x_{1} )^2 + (y_{2} - y_{1})^2}$

Points S and W.
$\sqrt{(3)^2 + (2)^2}$

$\sqrt{9+4}$

$\sqrt{13}$

~3.6

Points S and T
$\sqrt{(3 - 0)^2 + (-2 - 0)^2}$

$\sqrt{(3)^2 + (-2)^2}$

$\sqrt{9+4}$

$\sqrt{13}$

~3.6

Points T and U
$\sqrt{(3 - 2)^2 + (-2 + 5)^2}$

$\sqrt{(1)^2 + (3)^2}$

$\sqrt{1+9}$

$\sqrt{10}$

~3.1

Points U and V
$\sqrt{(2+2)^2 + (-5 + 5)^2}$

$\sqrt{(4)^2 + (0)^2}$

$\sqrt{16}$

~4

Points V and W
$\sqrt{(-2+3)^2 + (-5 + 2)^2}$

$\sqrt{(1)^2 + (-3)^2}$

$\sqrt{2+9}$

$\sqrt{11}$

~3.3

Add all these together.

3.3 + 3.1 + 4 + 3.1 + 3.6
≈17

How would you explain triangle classifications in your own words?

balandron [24]

Answer:

A triangle has three sides, three vertices, and three angles. The sum of the three interior angles of a triangle is always 180°.

The sum of the length of two sides of a triangle is always greater than the length of the third side.
