You downloaded a video game to your computer. You have a 60-minute free trial of the game. It takes 5 minutes to set up the game
Romashka [77]

In 60 minute trial, 5 minutes will be taken to set it up. You will have 60-5=55 minutes remaining.

Each level requires 7 minutes, so you can play \frac{55}{7} levels.

So you can play max 7 levels for free (8th level can't be completed)


The inequality, thus, can be written as:

5+7l\leq 60


ANSWER: 5+7l\leq 60

vivado [14]
There are several information's already given in the question. based on those information's, the answer can be easily determined.

Then
Volume of the box = Length * height * width
                              = 10 * h * 2h cubic cm
                              = 20h^2 cm^3

What are the zeros of the parabola whose equation is y = x2 + 8x + 15
Sedbober [7]

9514 1404 393

Answer:

  (1)  -5 and -3

Step-by-step explanation:

Descarte's rule of signs tells you the lack of sign changes among the coefficients means there are <em>no positive real roots</em>. That eliminates all answer choices except the first one.

__

If you want to go to the trouble, you can factor the equation:

  y = (x +3)(x +5)

These factors are zero when x = -5 and x = -3.
