90
Yes it is. 3x30=90
I think the real question here is what is 3X30 Its 90.
There are 3 feet in a yard so 3x30=90
I think that 23x38=874 because you can split it up like this:(20x30)+(3x8)+(3x30)+(8x20)=874.
1x90, 2x45, 3x30, 5x18, 6x15, 9x10 2x3x15, 2x5x9, 3x5x6
there are 30 days in November 2/3x30/1=20 days

Factors of 40 : 1X40 , 2X20 , 4X10 , 5X8 Factors of 90 : 1X90 , 2X45 , 3X30 , 5X18 Common factors : 1,2,5
it is aprox 3 months if each monthis is about 30 days 3x30 is 90 so approx 3 months mabey a bit less
inverse matrix. x1+x2+x3=3,000 -x1+5x2=0 2x1-3x3=0.
1x30=30 2x30=60 3x30=90 4x30=120 5x30=150 6x30=18030, 60, 90, 120, 150 and so on.
