a cube has a lateral surface area of 64 sq. m find the surface area of the cube.

Step-by-step explanation:

step 1. a cube has 6 sides which is made up of 4 lateral surfaces and 2 bases

step 2. 4 sides have 64m^2 of area or 1 side has 64/4 = 16m^2 of area

step 3. the surface area (total) of the cube is therefore 16x6 = 96m^2.

a) y = -3x +2

b) y = 1/2x -6

these 2 can be combined into one equation.

-3x +2 = .5x -6

8 = 3.5x

x = 8 / 3.5 = 2.2857142857

y = -3 * (8 / 3.5) +2

y = (-24 / 3.5) + 2

y = -4.8571428571
