Which of these inequalities has no solutions?

B is the one without a solution, because it states that a square root is less than a negative number. if √x is less than a negative value, then there isn't a number that you can plug into x that would make the inequality true. the square root of negative numbers creates an error (or an invisible number) so any values less than 0 plugged in for x don't satisfy the inequality. any positive numbers only give you positive square root results, so you don't get anything less than -17. for example:

√(36) < -17
6 < -17 is false.

WhaThe factorization of x2 + 3x – 4 is modeled with algebra tiles.t is the factored form of x2 – x – 2?
Nataly [62]

Answer:

  x^2 -x -2 = (x -2)(x +1)

Step-by-step explanation:

To factor x^2 -x -2, you look for factors of -2 that have a sum of -1:

  -2 = (-1)(2) = (1)(-2) . . . . . the latter pair has a sum of -1

Then these are the constants in the binomial factors:

  x^2 -x -2 = (x +1)(x -2)

_____

<em>Comment on the question</em>

The fact that x^2 +3x -4 is modeled with algebra tiles seems to be irrelevant to the question that is actually asked.

Chad drove 168 miles in 3 hours. How many miles per hour did Chad drive?
igor_vitrenko [27]


°° Let's see -

Basically, you divide the number of miles Chad drove by the number of hours it took. Then, it gives you the number of miles Chad drove in one hour. Let's try it!

168 ÷ 3 = 56

You can now see that Chad drove 56 miles in one hour.

Which of the following best represents the average speed of a fast runner?
Tpy6a [65]
For the answer to the question above, the easiest way to determine is changing every runner's speed into the same unit.

<span>First = 10 m/s </span>

<span>Second = 10 miles/min = 16090.34 / 60 m/s (As 1 mile = 1609.34 meter and 1 min = 60 sec) </span>
<span>Second = 260.82 m/s </span>

<span>Third = 10 cm/hr = 10*(0.01)/60*60 (As 1 cm = 0.01 m and 1 hr = 60*60 sec) </span>
<span>Third = 0.000028 m/s </span>

<span>Fourth = 10 km/sec = 10*1000 m/s (As 1 km = 1000 m and time is already in sec) </span>
<span>Fourth = 10000 m/s </span>

<span>So fastest would be the one who covers the largest distance in 1 sec. It would be the fourth one.</span>
