Solve 9x^2 + 12x – 24 = 0 using the quadratic formula.

Nataliya [291]

Quadratic formula = (-b +- sqrt(b^2 - (4ac))) / 2a

$\frac{ -12 + \sqrt{(12)^2 -((4)(9)(-24))}}{2(9)}$

and

$\frac{ -12 - \sqrt{(12)^2 -((4)(9)(-24))}}{2(9)}$

then simplify and solve

Order the ratios from least to greatest 16/24, 5 to 12, 6:13, 10:17, 13/28

saul85 [17]

Answer:

5/12, 6/13, 13/28, 10/17, 2/3

Step-by-step explanation:

First, simplify the ones that could be simplified.

2/3, 5 to 12, 6:13, 10:17, 13/28

(okay apparently only the first could be simplified)

You can look at all of them as fractions

2/3, 5/12, 6/13, 10/17, 13/28

Write a word sentence as an inequality. A number k minus 8.4 is greater than 21.

Travka [436]

Answer: k-8.4>21

Step-by-step explanation: K subtracted by 8.4 is greater than 21, so we start the equality off with our unknown variable K. Because K-8.4 is greater than 21, our symbol faces the direction of K-8.4 (symbol always faces the direction of the greater values).

Answer:

51.9

8.9

78.5

8.8

Explanation:

You round up if the number to the right is 5 or greater.

So, apply this to the numbers and the 8 in A rounds up, going to a 51.9.

The 9 does not round up because of the one.

The 5 also does not round up because of the 2.

The 7 does round up because of the 6.
