Answer:
1/9 chance
Step-by-step explanation:
Answer
105
Step-by-step explanation:
first bring 3 to the second power and get 9
then you have 7+8(9-2)
then add 7+8 and get 15
then you have 15(9-2)
then subtract 9-2 and get 7
then you have 15(7)
then times them and get 105
All real numbers greater than or equal to -8. You can see 3 is a minimum point because at 3 the numbers start to increase again. -8 is the lowest number and the function is increasing as x approaches infinity starting at 3.
The answer is D)6x2 square units.
A surface area of a cube is a sum of its sides' areas. A side of the cube is a square, and there are total 6 sides of the cube. Also, an area of the side of the cube is the area of the square, which can be expressed as a², where a is the length of the side. Therefore, the surface area (SA) of the cube is:
SA = 6*a² = 6a²
If side length is x, that means that a = x units.
After replacing it in the formula, you will have:
SA = 6a² = 6x² square units
