7 0
                  x² + 3x - 10 = 0
                                  x = -(3) ± √((3)² - 4(1)(-10))
                                                      2(1)
                                  x = -3 ± √(9 + 40)
                                                 2
                                  x = -3 ± √(49)
                                               2
                                  x = -3 ± 7
                                            2
                                  x = -3 + 7    U    x = -3 - 7
                                            2                       2
                                  x = 4    U    x = -10
                                        2                   2
                                  x = 2    U    x = -5

Find the geometric mean of 24 and 32
Maru [420]

Answer:

27√39

Step-by-step explanation:

To calculate the geometric mean we need to first of all multiply 24 and 32 and take the square root of it (i.e. 24*32 is 768, √768 is 27.712.....). However, in this case, we need to represent the answer in a simplified surd. To do this we need to find the highest possible perfect square that is below 768. Here it is 27 because 27*27 equals 729. Now we can go ahead and subtract 768 by 729. We get 39. So now we got two different surds. √729 and √39. We can simplify the √729 to 27. Thus our answer is the combination of both 27*√39 or 27√39.

Solve the system of equations - 8x + 3y = -17 and 3x - y = 7 by combining the<br> equlations.
NeTakaya

Given :

Two equations :

-8x + 3y = -17  ....1)

3x - y = 7        ....2)

To Find :

The solution of the system.

Solution :

Multiplying equation 2) by 3 and adding with equation 1), we get :

(-8x + 3y) + 3(3x - y) = -17 + 21

x = 4

Putting above value of x equation 2) we get :

12 - y = 7

y = 5

Therefore, solution of system is ( 4,5 ).
