First think of the form a^2 + 2c + c^2
c in the question is clearly 3.
So we need first to add 8 for both sides to get rid of -8 and then add 9 to complete the square.
So it will be (x^2+3)^2 = 17
So the choice number 3 is the answer.
Hope this helps!
6x+1=2(x+3)+4x has no solution because if you simplify it you get 6x+1=6x+3 which can not have any solution, since anything you substitute for x will not give you a solution.
4x-1=4(x+3) also has no solution. if you simplify you get 4x-1=4x+3 so no value that you substitute for x will give you a solution
Answer:
25
Step-by-step explanation:
he got an 80 so if that was his grade by answering 20 questions right then the correct answer would be 25 questions
5,7,8 they all equal 21, 21 divided by 3 is 7
