Not sure what 14 is asking?
15 would be 16.
The square root of width squared plus length squared equals the diagonal.
So if you just change the order of the equation you can find the length.
Double check it by doing it both ways to see if your answer is right.

Answer:
IT is B. 2.9
Step-by-step explanation:
X² − 6x + 7 = 0
Let's complete the square [x²-6x+(??)²] -(??)² +7 = 0
As you noticed we have added the unknown square & also subtract the same so that not to change the equation
The question now is to calculate this square (??)²
We know that the middle term (6x) is twice the square root of the 1st times the square root of the 2nd, That is 6x=2x (multiply) √(??)²
6x = 2x?? & ??=6x/2x===> ?? =3 & (??)² =9
Hence plug (??)² into the equation above:
x² - 6x + 9 - 9 +7 =0
(x²-6x+9) -9 + 7 =0
(x-3)² -2 =0 ====> (x-3)² = 2 (that is B)
Hello!
y=4x+2 is the steeper line. The bigger the slope, the steeper the line.
Hope it helps!
