Solve 9x2 + 6 = 12x

Mathematics
1 answer:
Oksana_A [137]4 years ago
7 0

Step-by-step explanation:

9x² + 6 = 12x

3x² + 2 = 4x

3x² − 4x + 2 = 0

Use quadratic formula.

x = [ -b ± √(b² − 4ac) ] / 2a

x = [ -(-4) ± √((-4)² − 4(3)(2)) ] / 2(3)

x = [ 4 ± √(16 − 24) ] / 6

x = [ 4 ± √(-8) ] / 6

x = (4 ± 2i√2) / 6

x = (2 ± i√2) / 3

Rearrange the equation so uuu is the independent variable.<br> -12u+13=8w-3
Semmy [17]

Answer:

u = 8w-16 /-12        or  =  - 8w-16/12 both mean the same due to the a/-b- = -a/b rule. Then you can factor out the rest. note the fnew subtraction changes mean the same as - (a/b) and should show without brackets as a centre pointing whole fraction subtraction sign.

Step-by-step explanation:

-12u -13 = 8w-3

-12u+13 -13 = 8w-3-13     Eliminate -13 by +13 both sides

-12u = 8w-16                      So you are left with one value left side.

-12u/-12  =  8/-12 - 16/-12   Then divide all values by -12 to find value for u and keep the subtraction as 8 never had subtraction sign and no multiplication .

u = 8w-16 /-12                   Then you can factor out the rest

This has made u the independent variable then you have a choice to continue showing or ignore u; as u =

=       -  8(w-2)/12       Step 1   Factor with subtraction change from -12  to - central fraction

=         - 2(w-2)/3      Step 2   Simplify with new minus sign for central fraction to replace a/-b

The total number of fungal spores can be found using an infinite geometric series where a1 = 8 and the common ratio is 4. Find t
Dmitry [639]
The formula for infinite geometric series is equal to a1 / (1-r) where in this problem a1 is equal to 8 and r is equal to 4. In this case, r is not equal to less than 1. This means the sum should be infinity and cannot be determined definitely.

aron lei is making identical balloon arrangements for a party. He has 32 maroon balloons and 24 white balloons, he wants each ar
alexandr402 [8]

Answer:

The greatest number of arrangements that he can make if every balloon is used is 8.

Step-by-step explanation:

The greatest number of arrangements will be the greatest common factor between 24 and 32.

GCF of 24 and 32:

We keep factoring both numbers by prime factors, while they can both be divided by the same number. So

24 - 32|2

12 - 16|2

6 - 8|2

3 - 4

There is no factor for which we can divide both 3 and 4. So the GCF is 2*2*2 = 8.

This means that the greatest number of arrangements that he can make if every balloon is used is 8.
