C+a+b=p
move a to the other side
sign changes from +a to -a
C+a-a+b=p-a
C+b= p-a
move +b to the other side
C+b-b= p-a-b
Answer:
C= p-a-b

Answer:
It has to be 16in since 256 is obviously to much and 4 and 8 are too little
Step-by-step explanation:
There are 1000 grams in a kg, so 6300x1000=6,300,000 grams
Well the equation is (A^2)+(B^2)=(C^2)
A= x
B= 2x
C will always be the longest side because it is the Hypotenuse = 25
So if you plug in those numbers into the equation...
(x^2) + (2x^2) = (25^2)
x^2 + 4x^2 = 625
Combine like terms
5x^2 = 625
Divide by five to both sides
x^2 = 125
Then Square root,
x = sqrt(125)
x = sqrt(25* 5)
x = 5sqrt(5)
