Answer:
x = - 3 ± √27 or if you want it in decimal form correct to nearest hundredth:
x = -8.20, 2.20.
Step-by-step explanation:
x^2 + 6x - 18 = 0
this will not factor so we use completing the square:
x^2 + 6x = (x + 3)^2 - 9 so:
(x + 3)^2 - 9 - 18 = 0
(x + 3)^2 = 27
x+ 3 = ±√27
x = - 3 ± √27
A linear system can have infinite solutions if both systems represent the same line. if a linear system down not represent the same line then it can only have one or no solutions. No solution is if the system is representing parallel lines and one solution represents an intersection of the two lines. in a nonlinear system you can have infinite or up to a maximum of intersections as the highest degree of the systems.
C) 15.5 pounds
Maya's group: 14.8 + 12.5 = 27.3
Will's group: 11.8 + ___ = 27.3
27.3 - 11.8 = 15.5
A 30 60 90 triangle is when one angle is 30, another is 60 and the other one is 90. and the side across from the 30 is x(1) and the one across from 60 is x rote 3(rote 3) and across from 90 is 2x(2).
