The GCF for 45x^3 and 40x^2 is 5x^2. This leaves you with 9x and 8. These cannot be further simplified as there are no further common factors.
The GCF for 16 24 18 is 2.
The GCF is: 1
The GCF is 2x.
The GCF is xy
Since x is a factor of 40x2, it is automatically the GCF.
The GCF is 5x
The GCF for 45x^3 and 40x^2 is 5x^2. This leaves you with 9x and 8. These cannot be further simplified as there are no further common factors.
80
40 x 2 = 80
4x(10x + 1)
5(4x - 3)(2x + 5)
2(4x - 1)(5x - 6)
The solution to the equation 40x2 - 9x - 10 = 0 is either 5/8 or (-2/5)40x2 - 9x - 10 = 0(8x - 5) (5x +2) = 0x = 5/8 or x =(-2/5)
80 minutes. (40 minutes each half) = 40x2 minutes for a NRL match
720 = 9 x 80
Mental math is basically math in your head so for example 40x2=80 so I did that in my head
