You are moving a total from - 13  to + 22. That alone is enough to make someone wonder why they live where they live. (The weather where I live can can do exactly this). 

What is the range of the temperature?
You might think it was -13 to 22. It sounds like it could be 9 degrees. 22 - 13 = 9. 

That is not right. The actual movement is absolute value of (-13) which will be added onto 22.

So the temperature movement is
13 + 22 = 35 degrees.

Hours.
The hours are not as hard to figure out. From 3am to 10 am is 7 hours

Degrees per hour
<em>Formula </em>
Degrees / hour = degrees / hour
degrees = 35 degrees
hour = 7 hours.

Degrees / hour = 35 degrees / 7 hours = 5 degrees / hour.

The average change of temperature per hour is the difference in temperature divided by the difference in hours.

3 a.m.     10 a.m.  ----> difference in time: 10 - 3 = 7
-13           22         ----> difference in temperature: 22 - (-13) = 35

average change of temperature per hour: 35/7 = 5

Answer: 5 degrees per hour

Super confused definitely need help on this
Marat540 [252]

Answer:

(x-5)(x+8)=x^2+3x-40

Step-by-step explanation:

So we have the expression:

(x-5)(x+8)

To multiply, distribute the left to the terms on the right:

=(x-5)(x)+(x-5)(8)

Distribute:

=(x^2-5x)+(8x-40)

Combine like terms:

=(x^2)+(-5x+8x)+(-40)

Simplify:

=x^2+3x-40

Therefore:

(x-5)(x+8)=x^2+3x-40

Meanings of inequalities :

< less than
> more than
= equal

convert both fractions to their common denominators , which is 40.

7/2/5 = 7/16/40
7/3/8 = 7/15/40

as you can see, 7/2/5 is bigger. thus the answer is > .
