You subtract 4/9x frm 8/9x which is 4/9x = 8 then you multiply 9 to 8 so it is 4x = 72. After that, you divide 4 from 72 and get 18
I believe that the answer would be 8, but I'm not exactly sure.
I hope that this helps ~
Rewrite s = 4 + sqrt(s+2) as s-4 = sqrt(s+2)
Square both sides: s^2 - 8s + 16 = s + 2
combine like terms: s^2 - 9s + 14 = 0
Factor this: (s-7)(s-2)=0
Solve for s: s={7, 2}
Answer:
0.92
Step-by-step explanation:
We turn 23/25 into 92/100. And since 100 is the denominator the decimal is 0.92
