Answer:

8640

Step-by-step explanation:

Take 2.4 hours, And 1 hour is 60 minutes, and 1 minute has 60 seconds, so 1 hour has 3600 seconds, Do one more hour and you have 7200 seconds, Now you need to add another .4 hours, .4 hours is equal to 40 minutes, so how many seconds are in 40 minutes? 1440 seconds are in 40 minutes, so add 7200 and 1440 and you get 8640.

Express the area of the rectangle shown below as a trinomial
zzz [600]
As we know that the area of a rectangle is -

length × Breadth

So, here length = (3n+1)

Breadth = (2n-5)

Area of rectangle
= (3n+1)(2n-5)

= 3n(2n-5)+1(2n-5)

= 6n² - 15n + 2n - 5

= 6n² - 13n - 5

Answer) Area of rectangle is 6n² - 13n - 5

2l+2w=perimeter <= equation for perimeter 
<span>w+4=l <=length is 4 greater than width </span>
<span>2w+2(w+4)=24 <= plug in the l in the first equation with the second equation </span>
<span>2w+2w+8=24 <= solve the equation </span>
<span>4w=16 </span>
<span>w=4 </span>

The middle school is 2.72 Kilometers from Kim's house and 1.54 kilometers from Terri's house. How much farther in meter does Kim
TiliK225 [7]

Answer: 1,180  meters.

Step-by-step explanation:

Hi, to answer this question we have to subtract Terri's distance from the school (1.54) to Kim's distance from the school (2.72)

Mathematically speaking:

2.72 km - 1.54km = 1.18 km

Since the answer must be expressed in meters.

1000 meters = 1 kilometer

1.18 km x 1000 m/km = 1,180 meters.

Feel free to ask for more if needed or if you did not understand something.
