Answer:
hypotenuse
Step-by-step explanation:
It states that a2 + b2 = c2 for the sides of any right triangle (c is the hypotenuse, or longest side), AND it also states that if the three sides of a triangle obey this formula, they do form a right triangle. Since 6 is the longest sides, it would have to be the hypotenuse.
Unit rate = 3/8 : 1/6
We can also write this as:
3/8 / 1/6
Flip the 2nd fraction and multiply:
3/8 * 6/1
Multiply the numerators and denominators together:
18/8
Simplify by dividing the numerator and denominaotr by 2:
18 / 2 = 9
8 / 2 = 4
So we have:
9/4
Answer:
K = 42
Step-by-step explanation:
K/2 = 21
2* k/2 =2*21
k=42
That would be written as:

And the step-by-step equation would be:
→ we take the 2 to the right side of the equation and do the IO*
→we solve for 
→ final answer
*Ps - IO is not an existing term and stands for inverse operation. In this case, because when we take to 2 to the right side of the equation (the 2 is a power) it'll have to turn into a square root (because exponents and roots are inverse operations)
