√64 = 8 this is rational number
answer
√64
Since b is the midpoint BC is half the line so we can set up this equation
x+4+X+4=3x-8
and then solve like normal
2x+8=3x-8
16=x
once you have x then solve x+4
16 + 4 =20
AB is 20
Answer: 10/27

Your multiplying the top and bottom yw :)
Answer:
30
Step-by-step explanation:
For a triangular prism, the formula for volume is v=bh where b is the area of the base (72) and h is the height (20). 72x20=1440 so the volume is 1440 cm^3
As for surface area, you want to find the area of each of the faces. For the triangle faces the area is 72. For the three identical rectangle faces the area is 240. 240x3+72x2= 720+144=864cm^2
Hope this helped :)
