Step-by-step explanation:
1. Add 5 to both sides.
2. Divide both sides by 2.
3. Take the square root of both sides.
4. Subtract from both sides.
Answer:
-3 is the additive inverse of 3.
Step-by-step explanation:
Two numbers are additive inverses if they add to give a sum of zero. 3 and -3 are additive inverses since 3 + (-3) = 0. -3 is the additive inverse of 3.
What is the formula of additive inverse?
The additive inverse of a number is what you add to a number to create the sum of zero. So in other words, the additive inverse of x is another number, y, as long as the sum of x + y equals zero. For example, the additive inverse of the positive number 5 is -5.
Answer:
Yes
Step-by-step explanation:
We know it is written in scientific notation because we have a 10 to the second power 2. Since we have the number 10 to a certain power, being 2. It makes it written in scientific notation.
The shape of the cross-section is a rectangle and the area of the cross section is square units.

Analysis of a cube</h3>
Let be a cube whose <em>side</em> length is and lines and intersects the cube, then we have a <em>cross</em> section formed by points A, C, E, H. Since , , and , then by 45-90-45 right triangle.
In addition, we know that , and . Hence, we conclude that the cross-section is a rectangle. Hence, the area of the <em>cross-section</em> area is:
(2)
If we know that , then the area of the cross-section is:
The shape of the cross-section is a rectangle and the area of the cross section is square units.
