D. Have the same number of valence electrons
Answer:
a= 2b-x
Step-by-step explanation:
You have to isolate the variable by dividing each side of the factors that does not contain the variable "a".
You can use the Pythagorean Theorem:
a^2+b^2=c^2
x^2+x^2=(7√2)^2
2x^2=49*2 (combine like terms and square the 7√2)
x^2=49 (divide both sides by 2)
x=7 (square root both sides)
So the equation is 2x^2=98 (simplest form) and x=7
Hope this helps
