Let the bigger no. be X and the smaller no. be Y
X-Y=48
7-3=4
48÷4=12
X=12×7=84
Y=12×3=36
Equation in point slope form is given by y - y1 = m(x - x1); where m = (y2 - y1)/(x2 - x1).
y - 0 = (6 - 0)/(2 - 4) (x - 4)
y = 6/-2 (x - 4)
y = -3(x - 4)
310, 320, 330. any number ending in 0 is divisible by 2,5, and 10.
(X+4)(X-4) is the LCD because you just have to look at the denominators and see what factors or values are not already part of your LCD.
