Caleb is solving the following equation for xxx. x=\sqrt{x+2}+7x= x+2 ​ +7x, equals, square root of, x, plus, 2, end square root, plus, 7 His first few steps are given below. \begin{aligned}x-7&=\sqrt{x+2}\ \ \\ (x-7)^2&=(\sqrt{x+2})^2\\ \\ x^2-14x+49&=x+2 \end{aligned} x−7 (x−7) 2 x 2 −14x+49 ​ = x+2 ​ =( x+2 ​ ) 2 =x+2 ​ Is it necessary for Caleb to check his answers for extraneous solutions?

29 is the correct answer

step-by-step explanation:

total amount of money that he should pay if he has not used his duty free exemption is $98

step-by-step explanation:

given a united states citizen returning to the states declares the following items at the customs office: 3 shirts at $8.50 each 2 dresses at $27.50 each 1 pair of gold cuff links at $17.50 per pair. we have to find how much he pay

cost of 3 shirts if one cost at $8.50 is

cost of 2 dresses if one cost at $27.50 is  

cost of 1 pair of gold cuff at $17.50

so, total amount of money that he should pay if he has not used his duty free exemption is   $25.5+$55+$17.50=$98
