Is the system of equations is consistent, consistent and coincident or inconsistent?

Marcus needs to rewrite f(x) = x2 + 6x + 4 in vertex form.

Secant be and cf intersect at point d inside a what is the measure of cde

Maria found the least common multiple of 6 and 15. her work is shown below. multiples of 6: 6, 12, 18, 24, 30, 36, 42, 48, 54, 60, . . multiples of 15: 15, 30, 45, 60, . . the least common multiple is 60. what is maria's error?
