Answer:
5. A) two solutions
6. one solution
Step-by-step explanation:
5. A graph shows the curve has two x-intercepts, so two solutions. You can also figure this by looking at the discriminant:
b^2 -4ac = (7)^2 -4(-4)(8) . . . . a positive number
When the discriminant is positive, there are two real solutions.

6. The equation factors as ...
0 = 3(x +3)^2
This will have one real solution at x=-3.
Well.... You are a hexagon. Because really all the information you need to gather from this is that this shape has 6 sides. and what shape has 6 sides? A hexagon! therefore that is your answer. Hope this helped!

16x11 which equals 176 so that’s the area
-5 [(x^3+1)(x+4)]
-5 (x^4+4x^3+x+4)
-5x^4-20x^3-5x-20
