Answer:
The surface area of a cube = 6a2 where a is the length of the side of each edge of the cube. Put another way, since all sides of a cube are equal, a is just the lenght of one side of a cube. We have 96 = 6a2 → a2 = 16, so that's the area of one face of the cube.

Answer:
see explanation
Step-by-step explanation:
first fill out all sides of the triangle (use pythagorean theorem).
9^2 = 4^2+x^2
x^2 = 81-8 --> x^2 = 73 --> x = √73
csc theta --> hyp/opp
sin theta --> opp/hyp
cot theta --> adj/opp
hyp = 9, adj = 4, opp = √73
csc = 9/√73 --> 9√73/73
sin = √73/9
cot = 4/√73
10+5x=50
subtract ten from both sides
5x=40
divide five from both sides
x=8

Answer:
57 percent
Step-by-step explanation:
4 divided by 7= .57
- 57 reminder 1
- ________
- 7l 40
- 35
- 50
- so the total is 57
7x + 18 > -3
Subtract 18 from both sides,
7x > -21
Divide from 7,
x > -3
In short, Your Answer would be Option D
Hope this helps!
