12 x 18 = (12 x 10) + (12 x 8)
18 x 24 = (18 x 20) + (18 x 4)
12
3(4 + 6) = 3 x 4 and 3 x 6 = 12 + 18 = 30
432 x 12 inch x 12 inch bricks for an area 18 feet x 24 feet
12 x 18 = (12 x 10) + (12 x 8)
4 x 18 = (4 x 10) + (4 x 8)
The LCM of 18, 10 and 12 is 180. 18 = 2 x 3^2 10 = 2 x 5 12 = 2^2 x 3 lcm = 2^2 x 3^2 x 5 = 180
12*90 = 12*(100-10) = 12*100 - 12*10 = 1200 - 120 = 1080.
18 x 1 = 18 18 x 2 = 36 18 x 3 = 54 18 x 4 = 72 18 x 5 = 90 18 x 6 = 108 18 x 7 = 126 18 x 8 = 144 18 x 9 = 162 18 x 10 = 180 18 x 11 = 198 18 x 12 = 216
8 x 12 = (8 x 10) + (8 x 2) = 80 + 16 = 96
12 x 18 = 216 10 x 18 = 180 2 x 18 = 36 180 + 36 = 216
You need to be careful in how you write such questions as it is important to know if you mean: x - 12/2 = 18 or (x-12)/2 = 18 If x - 12/2 = 18 then x = 18 + 12/2 x = 18 + 6 x = 24 If (x-12)/2 = 18 then x - 12 = 18 * 2 x - 12 = 36 x = 36 + 12 x = 48
The GCF of 12 and 20 is 4. The distributive property states that 12 x 20 = 10 x 20 + 2 x 20 = 200 + 40 = 240 4(3 + 5)
x + 12 = 18 Therefore, x = 18 - 12 x = 6
18 x 27 = (18 x 20) + (18 x 7)
x + 10 = 18 18 - 10 = x 18 -10 = 8 x = 8
