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.
1x90 2x45 3x30 5x18 6x15 9x10 All of these work, and the opposites work as well. If both numbers are made negative, that works as well. There are an infinite number of fractional answers, so I will refrain from listing those
