Answer:
25. Its cubed.
Step-by-step explanation:
Answer:
x = - 4 ± 2
Step-by-step explanation:
Given
f(x) = x² + 8x + 4
To find the zeros let f(x) = 0, that is
x² + 8x + 4 = 0 ( subtract 4 from both sides )
x² + 8x = - 4
To solve using the method of completing the square
add ( half the coefficient of the x- term )² to both sides
x² + 2(4)x + 16 = - 4 + 16
(x + 4)² = 12 ( take the square root of both sides )
x + 4 = ± 
= ± 2 ( subtract 4 from both sides )
x = - 4 ± 2
Thus the zeros are
x = - 4 - 2 and x = - 4 + 2
If you wanted to compute for your budget for natural gas
this month using the data you have recorded about your consumption of natural gas
for the past four months, the best estimate to be budgeted this month would be
the average consumption for the past 4 months. To get the average, you have to
add the four numbers and divide it by four.
$112
+ $108 + $99 + $89 = $408/4 = $102
3x+y=9 ....(1)
3x-5y=15. ......(2)
-[3x-5y=15]
=> 3x+ y = 9
-3x+5y=-15
..........................
0 +6y=-6
so,y=-1
3x+(-1)=9
3x=10
x=10/3
The answer is seven (7)
Explanation:
There are eight red flowers
There are ten white flowers
There are five yellow flowers
Add those together.
8+10+5 = 23
Subtract from the total number of flowers which is thirty.
30 - 23 = 7
