60 x 1.5 is 90
3xx plus 5x -60 equals 0?
Doesn't have integer roots. Quadratic formula gives roots as 3.71 and -5.38.
How do you work out 3x squared -10x equals -5?
This is a quadratic expression in x. It cannot be solved because it is an expression: there is no equation to solve. Furthermore, the discriminant for the quadratic = (-10)2 - 4*3*(-5) = 100+60 = 160 which is not a square number. There are, therefore no rational factors. While it would be possible to give irrational factors, factorising a quadratic into linear terms containing irrational numbers is rarely useful.
Find the value of x in the equation x-40 equals 60?
x=100
What two numbers add up to -20 but multiple -60?
-80
What is the length and width of a rectangle that's area is 60 square cm and it's perimeter is 38 cm?
Let the width be x and the length be y: xy = 60 2x+2y = 38 Divide all terns in the bottom equation by 2: xy = 60 x+y = 19 => x = 19-y Substitute the value of x in the bottom equation into the top equation: (19-y)y = 60 19y-y2 = 60 Rearrange the equation into a quadratic: -y2+19y-60 = 0 Solve by factoring or with the help of the quadratic equation formula: (-y+4)(y-15) = 0 So y = 15 or y = 4 it must be the former because it's larger Therefore: width = 4 cm and length = 15 cm
