Hello there!

y² + 6y + 5 = 0
Let's factor this equation.

(y+1)(y+5) = 0

y + 1 = 0                 y + 5 = 0
      y = -1                      y = -5

So your answers are...
y = -1 , y = -5

Equation
-------------------------------------------------
y² + 6y + 5 = 0

-------------------------------------------------
Factorize it
-------------------------------------------------
(x + 5)(x + 1) = 0

-------------------------------------------------
Apply the zero product property rule
-------------------------------------------------
x + 5 = 0 or x + 1 = 0

x = -5 or x = -1

4. See if you can find "like-terms" in the expression and
WITCHER [35]

Answer:

After finding like terms and solving, we get \mathbf{3x^2+3x+16}

Step-by-step explanation:

We need to find like terms and simplify the expression 4- 2x + x^2 + 5x + 12 + 2x^2

Like terms: The terms who have same variable and exponent are called like terms.

So, Combining like terms and solving:

4- 2x + x^2 + 5x + 12 + 2x^2\\=4+12-2x+5x+x^2+2x^2\\Now \ solving:\\=16+3x+3x^2\\Rearranging \ the \ terms:\\=3x^2+3x+16

So, after finding like terms and solving, we get \mathbf{3x^2+3x+16}

<u><em>Note: In the question given we have - and + sign with the term 5x</em></u> i.e 4- 2x + x^2 -+ 5x + 12 + 2x^2

I have solved using +5x, but if the term is -5x then the solution will be:

4- 2x + x^2 - 5x + 12 + 2x^2\\=4+12-2x-5x+x^2+2x^2\\Now \ solving:\\=16-7x+3x^2\\Rearranging \ the \ terms:\\=3x^2-7x+16

So, the answer will be: \mathbf{3x^2-7x+16}

Maxine types 294 words in seven minutes how many words does Maxine type in 11 minutes
Inga [223]
First we find the unit rate which would be how many words in 1 minute...

294/7 = 294 ÷ = 42 wpm

Now we multiply by how many minutes to find the total...

42 wpm × 11 min = 462 words.

Insert a digit to make numbers that are divisible by 12 if it is possible 14…4
9966 [12]

Answer:  Insert a 6.  The number divisible by 12 is  14<em><u>6</u></em>4    

Step-by-step explanation:  Start by dividing 12 into the first two digits.

I am using old-fashioned long division.

       <u>1  2</u>

12 ) 14 <u><em>6</em></u>

     -<u>12</u>

         26.           this is the remainder, The next digit has to be a number that when divided by 12 will leave a remainder, that when paired with 4, will be evenly divisible by 12.

6 is that number . When you "bring down" the 6, you will be dividing 26÷12.  a  2 goes into the quotient, and in the next step 24 is subtracted from 26; the remainder is 2.

Bring down the 4 and divide 12 into 24.  The result is 2 as the quotient.  2 ×12 =24 .  24- 24 is 0

1464 ÷ 12 = 122
