Step-by-step explanation:
I don't really know I just used a calculator
Answer:
3m
Step-by-step explanation:
3m/m-6 × 5m³ - 30m²/ 5m²
We'll multiply numerators first = 3m × 5m³ - 30m²
Denominators = 5m² ( m - 6)
= 5m³ - 30m²
Therefore numerator / denominator
= 3m ( 5m³ - 30m²) / 5m³ - 30m²
Note :5m³ - 30m² ÷ 5m³ - 30m² = 1
Therefore answer
= 3m × 1 = 3m
