Hiya!
x is going to work out to 25.
———————————————
so first put the numbers into the equation you’ve been given.
pressure is 3, force is 1500 so 3=1500/area
then rearrange this equation so that you’re finding area.
area=1500/3
and 1500/3 gives you 500.
so 500 is the area.
area is length multiplied by width, so 20 multiplied by x.
total/width will give length, so 500/20 will give x.
500/20=25
so x is 25.
Answer:
The last three terms are true.
Step-by-step explanation:
The last three statements are true. Yes, the numerator has 3 terms: x^2 + 6x - 2. Yes, the denominator has 2 terms: 6x - 5. Yes, that denominator is a single factor.
No, the numerator does not have three factors. It does, however, have three terms. No, 6x in the numerator does not cancel out the 6x in the denominator.

Answer:
- -2.2(6) +1.8(4) . . . temperature change
- 42 °C
Step-by-step explanation:
At the end of the first 6 hours, the temperature change was ...
(-2.2 K/h)(6 h) = -13.2 K
The change in the next 4 hours was ...
(1.8 K/h)(4 h) = 7.2 K
Then the total change over the 10-hour period was ...
(-2.2)(6) +(1.8)(4) . . . . . expression for temperature change
This evaluates to -13.2 +7.2 = -6.
__
The final temperature is the sum of the initial temperature and the temperature change:
final temperature = 48 °C -6 °C = 42 °C

<em>Additional comment</em>
When temperature is measured on the Celsius scale, a change of 1 degree is called a kelvin (K).
