Solve the equation for x, where x is a real number (5 points): <br> 2x^2 + 15x + 4 = 0
vitfil [10]
To find the solutions to this equation, we can apply the quadratic formula. This quadratic formula solves equations of the form ax^2 + bx + c = 0
                           x  = [ -b ± √(b^2 - 4ac) ] / (2a)
                           x = [ -15 ± √((15)^2 - 4(2)(4)) ] / ( 2(2) )
                           x = [-15 ± √(225 - (32) ) ] / ( 4 )
                           x = [-15 ± √(193) ] / ( 4)
                           x = [-15 ± sqrt(193) ] / ( 4 )
                           x = -15/4 ± sqrt(193)/4
The answers are -15/4 + sqrt(193)/4 and -15/4 - sqrt(193)/4.

Jake carries a green a yellow and a black guitar pic in his pocket he randomly chooses a guitar pic from his pocket before every
Tomtit [17]
Green,yellow,and black = 3 probabilities if choose randomly
Next, since there are two concerts lets multiply 3 times 2 which will equal 6 for the denominator.
Third, since there are going to be one color chosen two times in a row it'll be 2 for the numerator.
It's going to be 2/6 but simplified it'll be 1/3.
