The height of a triangle is 4 m less than its base. the area of the triangle is 48 m^2. what is the length of its base?

(a) (8%) compute the probability of an even integer among the 100 integers 1! , 2! , 3! , until 100! (here n! is n factorial or n*(n-1)*(n-2) *… 1) (b) (16%) compute the probability of an even integer among the 100 integers: 1, 1+2, 1+2+3, 1+2+3+4, …., 1+2+3+… + 99, and 1+2+3+… + 100

Using the quadratic formula find the zeros of the given polynomial -5x^2+3x-11

Solve: 3x+y=6 4x-2y=18 show all work !
