Nikolay [14]

Answer: 4.64 kilograms

Four rock climbers started a climb and each person carried 5.8 kilograms of climbing equipment.

aleksandr82 [10.1K]

Answer:

⇛-4x².

Step-by-step explanation:

Given expression;

-32x^4 ÷ 8x^2

  • -32 = -2*2*2*2*2*x*x*x*x
  • 8x^2 = 2*2*2*x*x

So, -32x^4 ÷ 8x^2

⇛-32x^4/8x^2

⇛(-2*2*2*2*2*x*x*x*x)/(2*2*2*x*x)

⇛-2*2*x*x

⇛-4x² Ans.
