1) vertical (they share a vertex, or midpoint)
2) adjacent (they are next to each other)
Answer:
x equals -1 and it also equals -13. They are both considered the roots.
Step-by-step
- (x+6)^2= 49 to get rid of the exponent square root each side of the equation.
- (x+6)= √49 Find square root of 49.
- (x+6)= ±7 It could be positive 7 or -7 because both of them squared equal 49. Now solve for each possible equation, (x+6)= 7 and (x+6)=-7.
- (x+6)=7 subtract 6 from each side.
- x= 1
- (x+6)=-7 Subtract 6 from each side.
- x=-13
- So the answers are -13 and 1.
Answer:
400
Step-by-step explanation:
1189 becomes 1000
597 becomes 600
therefore 1000-600= 400

Answer:
8.06
Step-by-step explanation:
Use Pythagorean theorem to determine the hypotenuse
Since the values are equally likely and equally spaced, their mean is the middle one.
the mean is 1/5
The variance is the average of the square of the deviations from the mean.
σ² = (1/3)((-1/10)² + 0² + (1/10)²) = 2/300
the variance is 2/300
