Identify the like terms:
4x - 7+ 6y + 2x + x + 16 - 3x

4x−7+6y+2x+x+16−3x

=4x+−7+6y+2x+x+16+−3x

Combine Like Terms:

=4x+−7+6y+2x+x+16+−3x

=(4x+2x+x+−3x)+(6y)+(−7+16)

=4x+6y+9

=4x+6y+9

Answer/Step-by-step explanation:

Volume of a sphere = ⁴/3πr³

1. r = ½ of 14.4 = 7.2 in.

Volume = ⁴/3 × π × 7.2³ = 1563.46 ≈ 1563.5 in.³

2. r = 6 yd

Volume = ⁴/3 × π × 6³ = 904.78 ≈ 904.8 yd³

3. r = 8 mm

Volume = ⁴/3 × π × 8³ = 2144.66 ≈ 2144.7 mm³

4. r = ½ of 13.5 = 6.75 cm

Volume = ⁴/3 × π × 6.75³ = 1288.25 ≈ 1288.3 cm³

5. r = 4.7 in.

Volume = ⁴/3 × π × 4.7³ = 434.89 ≈ 434.9 in.³ (nearest tenth)
