40x1=40 40x2=80 40x3=120 40x4=160 40x5=200 40x6=240 40x7=280 40x8=320 40x9=360 40x10=400
It is equal to 1.8It is equal to 1.8It is equal to 1.8It is equal to 1.8
Angles are not necessarily equal, and sides are not necessarily equal in length.Angles are not necessarily equal, and sides are not necessarily equal in length.Angles are not necessarily equal, and sides are not necessarily equal in length.Angles are not necessarily equal, and sides are not necessarily equal in length.
It is the same. So they are equal
428 is equal to 428. No other number is equal to 428.
80
Since x is a factor of 40x2, it is automatically the GCF.
The GCF is 5x.
They are equal. One tenth of 400 is 40. 40x2=80 One tenth of 200 is 20. 20x4=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
40/60 is equal to any fraction that you multiply both the top and bottom numbers by the same number. 40/60 = (40x2)/(60x2)=80/120 40/60 = (40/2)/(60/2) = 20/30 etc
Mental math is basically math in your head so for example 40x2=80 so I did that in my head
