Nastasia [14]

Answer and Step-by-step explanation:

A. 4 inches: An object that's 4 inches is about 2.54 centimeters or 25.4 millimeters. An business envelope is typically about 4 inches by 9 inches for example.

B. 6 feet: A 6 feet object is quite big when compared to just 4 inches. A feet is 12 inches hence 6 feet is 72 inches. A very tall human being is typically 6 feet.

C. 1 meter: A meter is about 39.37 inches hence it is quite big when compared to a feet. A baseball bat is one meter long.

D. 5 yards: A yard is 36 inches hence a bit smaller than a meter. A trampoline could be 5 yards for example

E. 6 centimeters: one centimeter is 0.394 inches hence smaller than an inch. A 6 centimeters object for example is pencil for writing.

F. 2 millimeters: a millimeter is 0.0394 inches hence smaller than a centimeter and an inch. An orange seed could be 2 millimeters long

G. 3 kilometers: one kilometer is 39370.079 inches hence a kilometer is bigger than inches, meter, feet, yards, centimeters, millimeters. A very big tree could be 3 kilometers long

Step-by-step explanation:

x^3\left(2x^2+3x\right)

<u>Apply distributive law: </u>a\left(b+c\right)=ab+ac

  • x^3\left(2x^2+3x\right)=x^3\times \:2x^2+x^3\times \:3x
  • x^3\times \:2x^2+x^3\times \:3x
  • 2x^5+3x^4

A package of vinyl floor tiles contains 45 one-foot square tiles. Find how many packages should be bought to cover the rectangul
Aleksandr-060686 [28]
Okay so you should find the area and then divide it by 45

120*90= 10,800

10,800/45= 240

240 is the amount of packages you will need to cover the floor

Solve using elimination.<br> 3x − 5y = 18 <br> -10x + 5y = 10
olga55 [171]

3x - 5y = 18 over

-10x + 5y = 10

Add them because the 5y's have the right symbols for us to add

-7x = 28

Divide

x = -4

Now you can plug in -4 for x in one equation, I would use the first equation!

3(-4) - 5y = 18

-12 - 5y = 18

Add 12

-5y = 30

Divide

y = -6

Your solutions are going to be:

x = -4

y = -6

To check your work plug x and y into one equation:

3(-4) - 5(-6) = 18

-12 + 30 = 18

18 = 18

Since 18 does equal 18 you know that your solution's work!
