Solve the equation using the quadratic formula

Mathematics
1 answer:
amm18123 years ago
3 0

Answer:

Step-by-step explanation:

Rewrite this quadratic equation in standard form:  2n^2 + 3n + 54 = 0.  Identify the coefficients of the n terms:  they are 2, 3, 54.

Find the discriminant b^2 - 4ac:  It is 3^2 - 4(2)(54), or -423.  The negative sign tells us that this quadratic has two unequal, complex roots, which are:

     -(3) ± i√423        -3 ± i√423

n = ------------------- = ------------------

             2(2)                      4

What is a good comparison of the estimated sum and the actual sum of 7 9/12+2 11/12
earnstyle [38]
10 8/12 because you get an improper fraction when you add 9/12 and 11/12 (20/12) so you see how many times 12 goes into 20 which is only once. you see how many are left over from when you take 12 from 20. then you have you fraction which is 8/12. now you have to add the numbers which is 7+2=9 but 12 goes into 20 once so you add 1 to your number to make it 10. That's the answer, 10 8/12.

What is the value of x?<br><br><br><br> Enter your answer in the box.<br><br> x = ?
Tema [17]

The partial circles in each corner mean that all 3 angles are identical, which means this is an equatorial triangle. In an equatorial triangle all three sides are the same.


We can set two of the equations to equal each other and solve for x:


3x -5 = 2x +20

Add 5 to each side:

3x = 2x +25

Subtract 2x from each side:

x = 25
