The line on the graph looks as it is increasing, it is steadily going up to the right.
Median = 59
First Quartile = 57
Third Quartile = 62
Answer:
name them
A=(-2,5)
B=(-2,1)
C=(1,1)
sides:
AB=c=4
AC=b=√(3²+4²)=5
BC=a=3
then we do this
2p=a+b+c
2p=3+4+5=12
p=6
then we calculate the area:
√(p(p-a)(p-b)(p-c))
Area=√6(6-3)(6-4)(6-5)
Area=√(6×3×2×1)
Area=√36=6
Let the length of side of cube=x
One side length is increased by 4cm,so the length will be x+4
Another side will be doubled,so new length will be 2x
And the thIrd side will be same as it is.
So the volume of new rectangular prism will be=
x × (x+4) × 2x=450
i.e 2x³+8x²=450
dividing 2 on both sides we will get,
x³+4x²=225
i.e x=5
So original length of cube is 5inch (Answer)
