By looking at the table, we can see that the y values are equal to the x values multiplied by 3.
3x = 3*3 = 9
3x =3*9 = 27
3x=3*13=39
3x= 3*20= 60
So, it is a direct variation and the function is y=3x
2. (a+b)²=a²+2ab+b²
(5x-2)²=(5x)²-2×5x×2+2²
(5x-2)²=25x²-20x+4
4. (a+b)²=a²+2ab+b²
(2x+5)²=(2x)²+2×2x×5+5²
(2x+5)²=4x²+20x+25
∵a=4, b=20, c=25
∴a+b+c=4+20+25=49
