What is -3x^2-4x-4=0
ss7ja [257]

Answer:

<h2>no real solution</h2>

Step-by-step explanation:

-3x^2-4x-4=0\qquad\text{change the signs}\\\\3x^2+4x+4=0\\\\\text{use the quadratic formula:}\\\\\text{for}\ ax^2+bx+c=0\\\\\text{if}\ b^2-4ac0,\ \text{then an equation has two solutions:}\ x=\dfrac{-b\pm\sqrt{b^2-4ac}}{2a}

\text{We have}\ a=3,\ b=4,\ c=4.\\\\\text{Substitute:}\\\\b^2-4ac=4^2-4(3)(4)=16-48=-32

Four more than three times n equals -5
Verizon [17]
3n+4=-5

do the opposite of adding 4. this means you have to subtract 4 from 4. whatever you do to the problem, you must do to the answer. now subtract 4 from -5.

-5-4=-9

since 4-4=0, we can take 4 out of the equation. now you have:

3n=-9

now divide -9 by 3

-9/3=-3

n=-3

hope this helps :)

Savannah measure's the temperature of a liquid to be 24 Celsius. Convert to Fahrenheit
jek_recluse [69]

Answer:

The temperature of Savannah's liquid to the nearest degree Fahrenheit is 75.2.

Step-by-step explanation:

The general formula to convert celsius into fahrenheit is

F=(C*9/5)+32

F= 24 *9/5 +32

F= 24*1.8 +32

F= 43.2 +32

F= 75.2

Therefore, The temperature of Savannah's liquid to the nearest degree Fahrenheit is 75.2

Can someone please help me solve number 13?
oksian1 [2.3K]

If an exponent is negative you need to switch it to the other side.

So it would be 54v¼•w⅔

__________

18v⅔•¹¹/³•x5/7

Then you need to simplify it. So you would do 54÷18 to get 3.

NOTE: when you are simplifying it's dividing, so the answer you get goes where the larger number is. So in this case the 3 is where the 54 was.
