Phineas will cover a cube with paint that costs $5 per square foot. each edge of the cube is 8 feet long.
what is the least amount of money phineas will spend on paint?

$1920

Step-by-step explanation:

there are 6 sides of a cube. the sq footage, since it’s 8 ft in length, is 64 sq ft on each side. in total, that’s 384. 384 x 5 is 1920

x = -4

step-by-step explanation:

- 20 - 4(x + 3) = 4x

=> -20 - 4x - 12 = 4x

=> - 32 -4x = 4x

=> -32 = 4x + 4x

=> - 32 = 8x

=> -32/8 = x

=> -4 = x

answer: 12,000
