Answer:

2 (7 + n)

Step-by-step explanation:

2 (7 + n)

For this equation you need to put parenthesis to show that you need to add, then multiply.

I believe to do this, you would write the eqaution 2(7+x).

The question says twice the sum (addition) of 7 and a number. The x takes the place of a number. Putting it all together we get 2(7+x).

Hope this helps! If you appreciated my answer, please brainliest me!

The question is missing the figure which is attached below.

Answer:

The last box that has dimensions 8 in × 8 in × 10 in

Step-by-step explanation:

Given:

Volume of the soil = 924 cubic inches.

There are four different types of boxes that need to be checked whether they can accommodate all of the soil or not.

The volume of the box must be at least 924 cubic inches to accommodate all of the soil.

Now, volume of the first box is given as:

$V_1=l\times b\times h=20\times 5\times 10=1000\ in^3>924\ in^3$

Volume of the second box is given as:

$V_2=l\times b\times h=10\times 10\times 10=1000\ in^3>924\ in^3$

Volume of the third box is given as:

$V_3=l\times b\times h=10\times 20\times 6=1200\ in^3>924\ in^3$

Volume of the fourth box is given as:

$V_4=l\times b\times h=8\times 8\times 10=640\ in^3$

Therefore, only the volume of the fourth box is less than the total volume of the soil. So, last box is the correct option.

Can someone help me!! I’m trying to find equivalent measures! 15!points if you can help!

MaRussiya [10]

1000 mL = 1 L

0.85 L = (0.85 L)*(1000 mL/1 L) = (0.85*1000) mL = 850 mL

So, 0.85 liters is equivalent to 850 milliliters
