Answer:

The perimeter is 36 cm.

Step-by-step explanation:

The expression 2l +2w is used to find the perimeter of a rectangle with length l and width w.

Now, when the length is 14 cm and width is 4 cm, the perimeter will be :

2(14)+2(4)

= 28+8

= 36 cm

Hence, the perimeter is 36 cm.

Answer:

You can hold 188.19 or a rounded 188 pounds per cubic feet

Step-by-step explanation:

First we need to find the area which is 271

I found this using the formula 2(WL+HL+HW)

If you can fit 271 square feet then you need to divide that by 4 to find cubic feet.

if you do this you get 67.75 cubic feet

next divide 67.75 by 0.36

you get 188.19

Simplify this expression using the distributive property
jok3333 [9.3K]

Answer:

When you use the distributive property, you multiply the two numbers together, just like simplifying any product. You will also see another example where the expression in parentheses is subtraction, rather than addition. You will need to be careful to change the sign of your product.

Here another question on my math quiz "Lucas is making one dozen snacks for his team. He uses 1/4 cup of dried cherries and 2/4
Angelina_Jolie [31]

Answer:

3 cups of dried cherries and 6 cups of drief apricots.

Step-by-step explanation:

one dozen is 12. So,

substitute 1 in 1/4 to 12/4, and 2 in 2/4 to 24/4.

i said 24 for the last one since 2×12=24. so, now we just devide....

12/4=3 and 24/4=6. so you'd need 3 cups of dried cherries and 6 cups of dried apricots total.

Papessa [141]

Answer

3^{7y} * 81^{8y} * 3^9  * 27^{-9y} = 3^{7y} * (3^4)^{8y} * 3^9  *(3^3)^{-9y}          

                                =3^{7y} * (3)^{32y} * 3^9  *(3)^{-27y}\\\\=3^{7y +32y +9 -27y}\\\\=3^{12y+9}

Tip :    

\frac{1}{27^{9y}}  = 27^{-9y} = (3^3)^{-9y} = 3^{-27y}
