Answer:
x = -2 ± 452i
Step-by-step explanation:
x² + 4x = 117
x² + 4x - 117 = 0
if you solve this quadratic by using the quadratic formula you get:
x = -2 ± 452i
452i is an imaginary number that equals 
Answer:
Scores = 8
Step-by-step explanation:
To solve variation problems, you make mild assumptions and analogies
Let's score be represented with S
Let's Absences be represented with A.
Therefore
S varies inversely as A
S ~ 1/A
S = K/A
The K represents a contant notation so that we can easily figure the variation problem.
When Absences were 2
Scores were 12
S = K/A
12 = K / 2
Cross Multiply.
K = 24.
It means that, S = 24 / A.
For a student with 3 absences, the score would be:
S = 24 / A
S = 24 / 3
S = 8
Math is fun!
Answer:
C
Step-by-step explanation:
The diameter is about three times smaller than the circumference. So by trial and improvement, we can see that 24.5 would be the correct answer.
I could be wrong
The solution for this problem is:
To get the diagonal length of a square, multiply the length of one side by the square root of 2:If the length of one side is x.
length of diagonal = x √2
length of a diagonal = 4√2
length of a diagonal = 5.6569 feet
