User: y2 - 5y = 3

Weegy: y^2+5y+6=0 y^2+3y+2y+6=0 y(y+2)+2(y+3)=0 (y+2)(y+3)=0 y+2=0 - - - - - > y = -2 y+3=0- - - - - - - -> y = -3 solution set y = -2 and -3

User: x2 + 6x = - 9. Hint: This is a double root.

User: (x - 8)2 = 48

Weegy: The simplify answer for this problem is x to the second power/4 -y to the second power

y^2 + 7y = 18
y^2 + 7y - 18 = 0
(y - 2)(y + 9) = 0
y - 2 = 0 or y + 9 = 0
y = 2 or y = -9
the equation that could be used to solve y^2+7y=18 by factoring is y - 2 = 0 and y + 9 = 0

Weegy: 10% User: Find the distance between the points (-2, 4) and (5, 4). User: Choose the correct conic section to fit the equation. 49x 2 - 16y 2 = 784 Weegy: The answer is "Circle " User: The volume of a box(V) varies directly with its length(l). If one of the boxes has a volume of 288 cubic inches and a length of 12 inches, what is the constant of proportionality for the group of boxes? Weegy: 24 cubic inches User: Which of the following equations is of an ellipse with x-intercepts of (3, 0) and (-3, 0) and y-intercepts at (0, 1) and (0, -1)? Weegy: no slope means m = 0 in y = mx + b line through (- 3, 0) is y - 0 = 0(x + 3) Or y = 0 User: Select the property that allows m + 0 to be written as m. (More)
