Solve forn: -6(n-8) = 4(12-5n)+14n
Irina-Kira [14]

Answer:

0

Step-by-step explanation:

-6(n-8) = 4(12-5n)+14n

-6(n-8)=-6n+48 =  4(12-5n)+14n= 48-20n+14n

then 48-20n+14n<em> = 48-6n</em>

so you have

-6n+48 = <em>48-6n</em>

-6n+6n= n

n+48=48

n-48=48-48

n=0

nordsb [41]

Answer:

39 (the first option listed among the possible answers)

Step-by-step explanation:

Recall that the mean is the same as the average of the numbers you have listed, that is the addition of all divided by the number of entries you use:

mean = \frac{29+42+45+39+36+41+38}{7} =\frac{270}{7} =38.57

Therefore, rounding to the nearest integer, our answer s: 39

Which equation has the solutions x = 1+
BaLLatris [955]

Answer:

The last equation x2 - 2x -4 = 0

has solution  (x - 1)^2 - 5 = 0,   x  =  1 + root(5)  or  x = 1 - root(5)

Step-by-step explanation:

If a quadratic function has roots 1 and 5

f(x) = (x -1)(x- 5)

f(x) = x^2 - 6x + 5

Unless you meant.  -4 and 6  ?

g(x) = (x + 4)(x - 6)

g(x) = x^2 -2x -24

-------------------------

Or did you mean  x = 1 and x =4 ?...

x^2 + 2x + 4 = 0  :   complete square  x^2 + 2x + 1 + 3 = 0,   (x+1)^2 + 3 = 0

x^2 - 2x + 4 = 0 :  complete square:  (x -1)^2 + 3 = 0

0x^2 + 2x - 4 = 0,    2x - 4 = 0,  x = 2

x^2 - 2x - 4 = 0  becomes:   x^2 - 2x + 1 - 1 -4 = 0 ;  (x - 1)^2 - 5 = 0
