This is just a line there are infinitely many solutions or points...for every value of x there is a value for y which is three times x. Pick any x solve for y and that is one of the infinite number of ordered pairs produced by the equation.
y=3x (0,0),(1,3),(2,6),(3,9).....................
Hello, a sphere has zero vertices.
The answer is D..............
W = L - 15
WL = 76
(L-15)L = 76
L^2 - 15L - 76 = 0
(L-19)(L+4) = 0
L = 19 or -4
Since a length cannot be negative, the length must be 19 units.
The width is 19-15=4 units.
