We are given the expression of the equation of a circle that is x2 + y2 + 14x + 2y + 14 = 0. Using ocmpleting the squares: 
x2 + y2 + 14x + 2y + 14 = 0(x+7)^2 + (y+1) ^2 = -14 + 49 + 1(x+7)^2 + (y+1) ^2 = 36 center thus is at (-7,-1) and the radius is equal ot square root of 36 equal to 6.

I need help with this question please !!
RSB [31]

Answer:

100, because 180 - 50 - 90 = 40

The vertical angles theorem is applied, so now angle DCE is 40

And since CE = ED, its isosceles triangle, so base angles are equal, so 40 and 40.

180 - 80 = 100 = Angle E.

The perimeter of a rectangular field is 264 yards. If the width of the field is 54 yards, what is its length?
SIZIF [17.4K]
P = 2(L + W)
P = 264
W = 54

264 = 2(L + 54)
264 = 2L + 108
264 - 108 = 2L
156 = 2L
156/2 = L
78 <=== Length is 78 yards
