X=-6

If you divide both sides by -5 5/5 is 0 & 20/5 is 4 the next step is to subtract 2 from both sides. -4-2 is -6

\implies {\blue {\boxed {\boxed {\purple {\sf { \: x =  - 6}}}}}}

\sf \bf {\boxed {\mathbb {STEP-BY-STEP\:EXPLANATION:}}}

- 5 \: ( \:  x+ 2 \: ) = 20

➺ \:  - 5x - 10 = 20

➺  \: - 5x = 20 + 10

➺ \:  - 5x = 30

➺ \: x =  \frac{30}{ - 5}

➺ \: x =  - 6

Therefore, the value of x is -6.

\sf \bf {\boxed {\mathbb {TO\:VERIFY :}}}

- 5 \: ( \: x + 2 \: ) = 20

❥ \:  - 5 \: ( \:  - 6 + 2 \: ) = 20

❥ \:  - 5 \: ( \:  - 4 \: ) = 20

❥ \:  20 = 20

❥ L. H. S. = R. H. S.

Hence verified.

What is the probability that the sun will rise tommorow?​
zvonat [6]

Answer:

100 percent the sun will rise tomorrow but who is to say you will get to see the sun tomorrow? who is to say you won't have a heart attack and die on this material planet tomorrow and won't get to see the sun rise. or what if the sun sends out a solar flare and burns everyone to a crisp and completely demolishes our ozone layer allowing oxygen to excrete from the planet and cooking everyone with solar radiation all at the same time catastrophic winds and earthquakes demolish the planet because of loss of pressure from the gravity field held in check by the oxygen that has left the planet from a destroyed ozone layer leaving everyone to suffocate and die and excruciating death therefore yes the sun will rise tomorrow but certain events are to unfold we could never prognosticate

On paper, use the completing the square method to solve the equation x^2 + 16x + 2. Can anyone help me with this?
scoray [572]

Answer:

x = -8 ± √62

Step-by-step explanation:

An equation needs an equals sign.  I assume the expression equals zero?

x² + 16x + 2 = 0

To complete the square, start by making the leading coefficient 1 (which it already is).

Next, take half of the b coefficient, square it, and add the result to both sides.

(16/2)² = 8² = 64

x² + 16x + 64 + 2 = 64

Factor the perfect square:

(x + 8)² + 2 = 64

Solve for x:

(x + 8)² = 62

x + 8 = ±√62

x = -8 ± √62
