D. 2sqrt6
E. 6

Write the first half as an equation, solve for x. Then plug x into the 2 questions in the 2nd half and take the difference

anonymous · Answer

So,

7x = 24 +x     (subtract x from both sides)
6x = 24           (divide both sides by 6)
x = 4

x^2 = 4^2 = 16
sqrt x = sqrt 4 = 2

16 -2 = 14

Well, he wrote x and X, so could it be that they're two different variables?

anonymous · Answer

no same variable...in the question is says the 7x is 24 more then x.  That's what my equation says.....

7x = 24 + x ...plug in x to confirm
7(4) = 24 + 4
28 = 28
