Answer:
i think the answer is D
Step-by-step explanation:
Set them equal to each other then solve for X
I assume that it’s an equation so:
2x^3-4=0
x=(2)^(1/3)
699 is closet because as you subtract every number from 750, the smallest answer given is the closest to the number you started with.
Wa=0.5Wb, Ha=20, Hb is unkown
the area of rectangle a is : Wa*20
the area of rectangle b is : Wb*Hb
Rectangle a has 7 times the area of rectangle b: Wa*20=7*Wb*Hb
Replace Wa with 0.5Wb: 0.5Wb*20=7Wb*Hb => Hb=10/7
