To calculate 12 x 90, you simply multiply the two numbers together. 12 x 90 = 1080. This is because when you multiply a two-digit number by a two-digit number, you multiply the ones place of the first number by the ones place of the second number, and then the tens place of the first number by the ones place of the second number, and so on.
90 x 12 = 1080 months
If that's 12 x 90 feet, it's 1080 square feet. If that's 12 x 90 inches, it's 7.5 square feet.

There are 7 days in one week. Therefore, 90 days is equal to 90/7 = 12 remainder 6 or 12 weeks 6 days.
Cos(90 - x) = sin(x) so cos2(90 - x) = sin2(x)
90 * 12 = 1080
complementary angles add up to 90 degrees x+y=90 y=x+12 x+x+12=90 2x+12=90 2x=78 x=39 x+39=90 x=51 so the angles are 39 degrees and 51 degrees
90+x+72+30 = 180. If you add 90+72+30, you get 192. But to get 180 you have to subtract 12. 90+(-12)+72+30 =180 if x is -12
12*90 = 12*(100-10) = 12*100 - 12*10 = 1200 - 120 = 1080.
90 x 12 = 1080 months
7.5 x = 90x = (90 / 7.5) = 12
The value of x that solves the equation -243 = 90 - 9x is x = -12.
a negative timesa positive is negative a negative times a negative is positive -6 x - 2 = +12 -10 x -9 = + 90 12 + 90 = 102
there are 12 inches in 1 foot, so 90 x 12 = 1080 inches
A dozen is 12. So 7.5 x 12 = 90.
90 x ((2 x 12) - 4) degrees ie 1800o
1 x 180, 2 x 90, 3 x 60, 4 x 45, 5 x 36, 6 x 30, 9 x 20, 10 x 18, 12 x 15 and also 90 + 90.
