Solve for xx. Write the smaller solution first, and the larger solution second. X^2 + 12x + 27 = 0x 2 +12x+27=0
sineoko [7]

Answer:

x = -9, -3

Step-by-step explanation:

x^2 + 12x + 27 = 0

We need 2 numbers whose product is  + 27 and whose sum is + 12. These are 3 and 9. So the factors are:-

(x + 3)(x + 9)  and this = 0

So (x + 3) = 0  or x + 9 = 0

x = -3 , -9

Which statement about the following equation is true?
spayn [35]

The given expression is

3x^2 -8x +5 = 5x^2

We have to find the discriminant first . And for that, first we need to move whole terms of the left side to right side, that is

5x^2 -3x^2 +8x -5=0

2x^2+ 8x -5 =0

The formula of discriminant is

D =b^2 -4ac

Substituting the values of a,b and c, we will get

D = 8^2 -4(2)(-5)=64+40 = 104

And since the discriminant is greater than 0, or it is positive so we have two real roots.

Therefore the correct option is B .

A 20% acid solution is mixed with 20 liters of a 45% acid solution. How much of a 30% acid solution will result?
vaieri [72.5K]

Answer:

50 liters

Step-by-step explanation:

If x is the volume of 20% acid, then:

x (0.20) + 20 (0.45) = (x + 20) (0.30)

0.2x + 9 = 0.3x + 6

3 = 0.1x

x = 30

30 liters of 20% acid are needed, so there will be a total of 50 liters of 30% acid.
