Kay must buy approximately 5 bags of potatoes (rounded up) and it would result to $6.975. If possible, she should buy 4.66666667 bags and the cost would be $6.51.
Answer:
x = - 2 ±
Step-by-step explanation:
To solve the equation using the method of completing the square.
Given
x² + 4x - 7 = 0 ( add 7 to both sides )
x² + 4x = 7
add ( half the coefficient of the x- term )² to both sides
x² + 2(2) x + 4 = 7 + 4
(x + 2)² = 11 ( take the square root of both sides )
x + 2 = ± ( subtract 2 from both sides )
x = - 2 ± ← exact solution
Point Q is the circumcenter of triangle UWV.
This would have been a much easier problem if you had bothered to actually include a diagram. But given the description of the line segment lengths, you have a triangle with vertexes UWV and the points T, S, and R are bisectors of their respective sides. Point Q is the circumcenter of triangle UWV. One easy way to find the circumcenter of a triangle is to construct the perpendicular bisector of the triangle's sides and the point of intersection of those bisectors is the circumcenter.
