Rahul and Rajesh were asked to subtract 4x - 5 from x² + 3x - 5. Their solutions are given below. Rahul: (x² + 3x - 5) - ( 4x - 5) = x² + 3x - 5- 4x + 5 = x² - x
Rajesh: (x² + 3x - 5) - (4x - 5) = x² + 3x - 5- 4x - 5 = x² - x - 10
Who solved the problem correctly and what was the mistake made by the other?​

Tomas is making trail mix using granola and walnuts. he can spend a total of $12 on the ingredients. he buys 3 pounds of granola that costs $2.00 per pound. the walnuts cost $6 per pound. he uses the equation to represent the total cost, where x represents the number of pounds of granola and y represents the number of pounds of walnuts. he solves the equation for y, the number of pounds of walnuts he can buy. answer- b tomas added 6 to both sides of the equation instead of subtracting 6. just took the test

36x2 + 49y2 = 1,764 the foci are located at: (-√13, 0) and (√13,0) (0, -√13) and (0,√13) (-1, 0) and (1, 0)edit: the answer is (- the square root of 13, 0) and (the square root of 13, 0)
