Answer:
Answer below
Step-by-step explanation:
Yo uneed to find the Area/volume
The area of the rectangle is 2×(5cm×1cm)+2(3cm×1cm)+2(5cm×3cm)=10cm+6cm+30cm=36cm^2
Volume=5cm×3cm×1cm=15cm^3
Ratio: 36cm^2/15cm^3=12cm^2/5cm^3
The lines that Mark drew are perpendicular.
let y = x^2
4y^2 -21y + 20 = 0
solve for y
then substitute back in to get x
