You download 12 news songs to your phone. Then you delete 5 old songs.Write each amount as an integer.
Gennadij [26K]
Hey there! :D

When you have a value, it is usually positive.

For example, if I have 5 chocolate bars, then I have +5 chocolate bars. 

When you take away a value, it is usually negative.

For example, I have 3 chocolate bars away, then I would have 3 fewer chocolate bars. (-3) 

Integers are negative or positive whole numbers.

12 songs= 12 <== the integer

Delete 5 old songs= -5 <=== the integer

I hope this helps!

Lie is solving the quadratic equation by completing the square.
wel

we have

3x^{2} + 18x - 8 = 0

Step 1

Move the constants to the right side

3x^{2} + 18x = 8

Step 2

Factor 3 out of the variable terms

3(x^{2} + 6x) = 8

Step 3

Add 27 to both sides of the equation

3(x^{2} + 6x+9) = 8+27

3(x^{2} + 6x+9) = 35

Step 4

Write the polynomial as a binomial squared

3(x+3)^{2} = 35

therefore

the answer is

Factor 3 out of the variable terms.
