Answer:
So to find ratio for questions like these we do x/y
So the ratio for the first one is 5/7
The ratio for the second is 12/7 or 1 5/7
Step-by-step explanation:
The space diagonal will have length ...
... d = √(1² +4² +2²) = √(1 +16 +4) = √21
_____
This can be found using the Pythagorean theorem. A drawing can help. Find the length of any face diagonal, then use that length as the leg of a right triangle whose hypotenuse is the space diagonal and whose other leg is the edge length not used in the first calculation.
Answer:
4 and 5 can make this true.
Answer:
25
Extra Info:
Thank you for this !! But for anyone who seriosuy doesn’t know: If you do 5+5, five times, its the same as 5x5 !!
Another Example:
3x3=9
3+3+3=9
3+3=6 6+3=9
