Step-by-step explanation:

His dive once he hits the water and goes below the surface water line is in the same direction as his dive off the platform. That's very important when you start to consider direction. So you add. Be sure and read this paragraph again.

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.

-x^(2)-12=-87<br><br> Please explain your answer, and how I make the x positive

spayn [35]

Solve for x over the real numbers:
-x^2 - 12 = -87
Add 12 to both sides:
-x^2 = -75
Multiply both sides by -1:
x^2 = 75
Take the square root of both sides:
Answer: x = 5 sqrt(3) or x = -5 sqrt(3) both Answers are correct
