8 = 4*2
So 5*8 = 5*(4*2) which, by the associative property, = (5*4)*2
= 20*2
Can you do 20*2 more easily than 5*8?
If not, you need another round of associate property.
20 = 10*2
So 20*2 = (10*2)*2 = 10*(2*2) = 10*4
And if you cannot do 10*4 then this question is beyond you anyway and knowing 5*4 is not going to help.
2X10 would work, as would 5X4.
no. 6x8 =48. 5x4 + 1x4 =20 + 4 =24.
20
5x4 - 2x = x*(5x3 - 2) and that cannot be factorised further without invoking surds.
the product of 5x4 because 5x4=20 and 5+4=9
The answer is 20.
The Commutative Property (of Multiplication) says that 4x5 = 5x4. So, If 4x5 = 20, then 5x4 will also be 20.
2X10 would work, as would 5X4.
no. 6x8 =48. 5x4 + 1x4 =20 + 4 =24.
No It is not 5x4=20 and 5x100=500
5x is a common factor of all terms:- 5x(x3+4x2+9)
5x4 meters = 20m2 = 215.28 square feet.
something like 5x4=4x5.
The lug pattern for 69 Dart is 5x4" original.
