Step-by-step explanation:
24/15 = 1.6
Volume for rectangular prism is l x w x h
12cm x 6.5cm x 1.25cm = 97.5cm^3
Answer:
See below
Step-by-step explanation:
Remember that quadratic functions are parabolas when graphed. The solutions are where the parabola crosses the x-axis.
1. The vertex of the parabola in f(x) is (0, 9) which is above the x-axis and the parabola opens up. So the parabola does not cross the x-axis. Therefore the solutions are imaginary.
2. The vertex of the parabola in g(x) is (9, 0) which is on the x-axis and parabola opens up. Therefore, there is a double solution.
3. The vertex of the parabola in h(x) is (-1, -9) which is below the x-axis and the parabola opens up. Therefore, there are two real solutions.
I know this is a long explanation, but that is a way of looking at the problem.
Answer:
x=7
Step-by-step explanation:
5x-9=8x-30
8x-5x=-9+30
3x=21
x=21/3=7
