Answer:
280 m
Step-by-step explanation:
a² + b² = c²
450² + b² = 530²
202,500 + b² = 280,900
280,900 - 202,500 = 78,400
√78,400 = 280
Answer:
3.3075 liters of paint
Step-by-step explanation:
7.40 (red paint) + 6.26 (blue paint ) = 13.66 (purple paint)
He pours 13.66 liters of purple paint equally into 4 containers and has 0.43 liters left.
x + x + x + x = 13.66 - 0.43
4x = 13.23
x = 13.23/4
x = 3.3075
The area is 24n^2 - 32n + 8
