For this case what we must do is to use the formula of the resolvent in the following way:
x = (- b +/- root (b ^ 2 - 4 * a * c)) / (2 * a)
Where,
a = 1
b = -4
c = -38
Substituting the values:
x = (- (- 4) +/- root ((- 4) ^ 2 - 4 * 1 * (- 38))) / (2 * 1)
x = (4 +/- root (168)) / 2
x = (2 +/- root (42))
Answer:
x = 2 +/- squareroot 42
12 cm, use the pythagorean theorem: a^2+b^2=c^2
5^2+b^2=13^2
25+b^2=169
b^2=144
b=12
12 cm
Answer:
-3x + 4 -y = 0
Step-by-step explanation:
Answer: -11
Step-by-step explanation:
Work with the first group of numbers " (9+8-6) " equals 11
Next move to the second pair "(4-5) " equals -1
Lastly multiply, 11 x -1 = -1
To answer this question I believe you just need to subtract the two values
-12-(-27) = -12 + 27 = 15
The temperature dropped 15 degrees
hope this helped!
