Simplify (5x−2+3x^2)+(4x+3)

Mathematics
1 answer:
Art [367]3 years ago
5 0

Answer:

3x^2 + 9x + 1

Or

3x ( x + 3 ) + 1

Step-by-step explanation:

(5x - 2 +3x^2 ) + (4x + 3 )

To make this a little bit more easier to read, you can remove the parentheses:

5x - 2 + 3x^2 + 4x + 3

Now, write in a way so that the like terms are next to each other:

3x^2 + 5x + 4x - 2 + 3

Now simplify the 'x' terms to get:

3x^2 + 9x - 2 + 3

Now, simplify the integers (the ones with now variables with them) to get:

3x^2 + 9x + 1

If you want, you can factor out the 3x for two of the terms to get :

3x ( x + 3 ) + 1

Therefore, your simplest form can either be 3x^2 + 9x + 1 OR 3x (x + 3 ) + 1

I need help thank you
erma4kov [3.2K]

Answer:

≈ 5

Step-by-step explanation:

<u><em>You can use the Pythagorean Theorem to solve this:</em></u>

a^{2} + b^{2} = c^{2}

<u><em>Now plug in the numbers into the formula:</em></u>

6^{2} + b^{2} = 8^{2}

36 + b^{2} = 64

<u><em>Subtract 36 from both sides:</em></u>

36 + b^{2} = 64

-36        -36

_________

b^{2} = 28

<em><u>Square both sides:</u></em>

\sqrt{b^2} = \sqrt{28}

b = 5.29

b ≈ 5

NEED HELP ASAP ILL MAKE YOU BRAINLIEST
Hunter-Best [27]

y = 12000x + 35000


When Mr. Nicolas began recording, it means, at 0 hour, how many tortillas was produced?


Subs x by 0.


y = 12000.0 + 35000

y = 0 + 35000

y = 35000


When Mr. Nicolas began recording the data, 35,000 tortillas had already been produced


The total number of tortillas produced 2 hours after the he began, it means, when x = 2


y = 12000 . 2 + 35000

y = 24000 + 35000

y = 59000


The total number of tortillas produced 2 hours after he began recording the data was 59,000


The total number of tortillas produced _ hours after he began recording the data was 85,000


Now we have y but not x.


y = 12,000x + 35,000

85,000 = 12,000x + 35,000

85,000 - 35,000 = 12,000x

50,000 = 12,000x

x = 50/12

x = 25/6

x = 4,1666...

Rounding

x = 4,167

Solve<br> 2x + 4 - 3x = -11
Dvinal [7]

Answer:

x = 15

Step-by-step explanation:

1. Combine like terms

        2x - 3x = -x

2. Rewrite original equation

       -x + 4 = -11

3. Subtract four from both sides of the equation.

      -x + 4 = -11

           - 4     - 4

        -x  = - 15

4. Divide by -1 on both sides to get rid of the negative signs:

        x = 15
