Answer:
Step-by-step explanation:
start with 0
round 1 : lose 3 1/2
round 2: wins 28 1/2
round 3 : lose 3 1/2
0 - 3 1/2 + 28 1/2 - 3 1/2 =
28 1/2 - 7 =
21 1/2 <==== thats 21 and 1/2 points
Answer:
She subtracted the coefficients instead of dividing them
Step-by-step explanation:
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
The answer is 7/1, when you want to know a reciprocal, all you do to the fraction is flip it around. Hope this Helps!
