The length is 10 and the area is 100 because 6,8,10 is a pythagorean triple. 36 + 64 = 100 and the square root of 100 is 10. 10 ^ 2 is the area which is 100. If this is right could you possibly give me brainliest? Hope this helped.
Answer:
Step-by-step explanation:
Rewrite this as

Knowing that i-squared = -1:

Both i-squared and 100 are perfect squares, so this simplifies to
±10i
The volume of the rectangular prism can be found with the formula
v= length × width × height
V = 10×10×30 = 3000
the volume of the triangular prism can be found with
v = 1/2(base×width×height)
v=1/2×30×9×10 = 1/2×2700
v = 1350
Now add the two volumes together for the total volume...
3000+1350 = 4,350 in^3
Answer:
80
Step-by-step explanation:
28-28=0
0-12= -12
28+12 = 40
28-40 = -12
40 is the increase
40 is half of 80
So, the answer is 80
To check: -12 + 40 (half of a number; 80) = 28
