Umm, surface area of a cube = 6e^2 (six edge square) which is 6(3)sqaure = 54

If the edge is 3 you multiply it by 3 which gets you 9 you then multiply this by 6 since the cube has 6 sides

Given the domain {-4, 0, 5}, what is the range for the relation 12x, + 6y = 24?
Alinara [238K]

↣ Substitute all domains in the equation for the ranges.

12x+6y=24    

2x+y=4     ↣ Divide the whole equation by 6.

↣ Substitute x = -4 in the equation.

2(-4)+y=4\\-8+y=4\\y=4+8\\y=12

Our range is 12 when x = -4. In the choice there is only one choice that has range value as 12. Therefore, the answer is B.

↣ <em>If you want me to solve for all ranges then you can reply under this. Since there is only one choice that has 12 as range value, I decide not to continue. So If you want me to solve for all ranges then feel free to reply under this. ↣</em>

Two angles are vertical angles. If the angles are also complementary angles, what is the degree of the angle
jeyben [28]

Vertical angles are congruent according to the vertical angles theorem. If they are complementary as well, then they both sum up to 90 degrees. So, form an algebraic equation!

x+x=90 or 2x=90... Using the division property of equality, the angle measure (or x) equals 45...

Happy Solving!
