Answer:

  • x ∈∅

Step-by-step explanation:

<u>Simplifying the equation to solve for x:</u>

  • 7(x + 4) - 6(x + 3) = x + 5
  • 7x + 28 - 6x - 18 = x + 5
  • x + 10 = x + 5
  • 10 = 5, this is incorrect

Since the final equation is incorrect, there is no solution

An artist plans a sculpture by stacking two cubes. Write an algebraic expression the artist can use to find the volume of the sc
vesna_86 [32]

Answer:

V= 2x^3

The volume is 128cm^3

Step-by-step explanation:

Given

Cubes = 2

Sides = 4cm

Required

Determine an expression for its volume

Find the volume

Volume of a cube is:

Volume = x^3

Where x represents the length of a side

So, volume of 2 cubes would be:

V= x^3 + x^3

V= 2x^3

Solving (b): Volume when x = 4

Substitute 3 for x in V= 2x^3

V = 2 * 4^3

V = 2 * 64

V = 128

<em>Hence, the volume is 128cm^3</em>
