If this is a cube and each side is 6ft, each face will have an area of 6ft * 6ft, or 36ft. There are 6 faces on a cube, so 36ft * 6 = 216ft² as the surface area (it's also the same as 6³, fancy huh?)

Y=1/2×-6 ×=-4 what is the solution to the system of equations

Answer:

(-4, -8)

Step-by-step explanation:

Use the substitution method. x = -4, so y = (1/2)x - 6 becomes:

y = (1/2)(-4) - 6, or y = -2 - 6, or y = -8.

The solution is (-4, -8).

topjm [15]

Answer:

The number of ways are there to paint the four buildings is 48.

Step-by-step explanation:

I) let the first building be any color. Therefore the first building can be painted with any of the 4 colors.

Therefore the first building can be colored in 4 ways.

ii) the second building can be colored in 3 ways since it cannot be colored the

same color as the first building.

iii) the third building can also be colored in 3 ways.

iv) the last building can be colored in 2 ways because it cannot be the same color as the first building or the color of the adjacent building.

Therefore the total number of ways the buildings can be colored = 4 $\times$ 3 $\times$ 3 $\times$ 2 = 48.
