There were 35 students in a class. They were given math books (each priced at $0.55) and other books the total value of which was n dollars. How much money was spent to provide the students with all these books.

Xto the second power plus 14x plus 48. what are the factors? we are doing factoring trinomials with a=1

Me solve this problem, and someone clearly explain to me how to solve it.1.) use the value of the discriminant to determine if the given trinomials has 2 real solutions, 1 real solution, or no real solutions.a.  x2  − 4x  − 7 = 0b. 4r2  + 11r  − 3 = 0c. 3m2  + 7 = 0d.  t2  + 2t  + 1 = 0

Which of the following pair(s) of circles have las a common external tangent? select all that apply. a and b a and c b and c
