For this case we have the following equation:
x ^ 2 + 18x + 32 = 0
Rewriting we have:
x ^ 2 + 18x = -32
By completing squares we have:
x ^ 2 + 18x + (18/2) ^ 2 = -32 + (18/2) ^ 2
Rewriting:
x ^ 2 + 18x + (9) ^ 2 = -32 + (9) ^ 2
x ^ 2 + 18x + 81 = -32 + 81
x ^ 2 + 18x + 81 = 49
(x + 9) ^ 2 = 49
Answer:
(x + 9) ^ 2 = 49
option 1
Answer:
Mean, Mode, Median, Range, Standard Deviation.
Step-by-step explanation:
The completed sentences are as follows -
- The arithmetic average of a distribution of scores is the Mean
- The score that shows up most often is the Mode
- The score right in the middle of a distribution is the Median
- We determine how much scores vary around the average in a way that includes information about the Range of scores by using the Standard Deviation

(3x+4)+(5x+6)=90
8x+10=90
8x=80
X=10
3(10)+4= A
30+4=A
