The answer would be 11.6619037897 because if you make a triangle out of it the sides are 10 and 6 so a^2 + b^2 = c^2 and you get 136 and if you find the square root of that it is <span>11.6619037897</span>
<u><em>x=8 is the correct answer.</em></u> First you had to subtract by 5 from both sides of equation, and it gave us, . And then simplify, and it gave us, . Then you can multiply by 4 from both sides of equation, and it gave us, . And finally simplify, and it gave us the answer is 2*4=8, or <u><em>x=8 is the correct answer.</em></u>Hope this helps! And thank you for posting your question at here on brainly, and have a great day. -Charlie
