14 x 14 = 196 13 x 13 = 169 12 x 12 = 144196
12 x 9 - 13 = 95
169squared just means the number times itself 2 times 13 x 13 = 169For another example 12 squared is 12 x 12. The answer is 144169. 13 X 13 = 169
13 x 0 = 0 13 x 1 = 13 13 x 2 = 26 13 x 3 = 39 13 x 4 = 52 13 x 5 = 65 13 x 6 = 78 13 x 7 = 91 13 x 8 = 104 13 x 9 = 117 13 x 10 = 130 13 x 11 = 143 13 x 12 = 156 13 x 13 = 169
Just multiply the two numbers. If you multiply 12 meters x 13 meters, the result will be in square meters (as when you get the surface of a rectangle). But if you multiply (12) x (13 meters), the result will be in meters (as in: how many meters do you walk when you walk a distance of 13 meters, 12 times?)
X-12=13+12 +12x=2525

15 x 13 x 12 is equal to 2,340
14 x 14 = 196 13 x 13 = 169 12 x 12 = 144196
12*13=156
13 x 12 x 8 =1248
The question seems to be saying: 3X + X/4 = 12 That can be worked as follows: x/4 = 12 - 3x x = (12-3x) * 4 x = 48 - 12X x + 12x = 48 13 x = 48 x=48/13 To evaluate: 3 * 48/13 = 144/13 (48/13) / 4 = 12/13 At this point you could divide it out, or continue to work in fractions. 144/13 + 12/13 = 12 (Simplify or divide out the fractions if you wish) 11-1/13 +12/13 = 12
156 square feet
156
To work out the area of a room multiply the width by the length.13 feet x 12 feet equals 156 square feet.Therefore the area of a 13 x 12 room is 156 square feet.
(5/6) / (13/12) = (5/6) x (12/13) = (5/1) x (2/13) = 10/13
lcm(8 12 13) = 312 Using prime factorisation: 8 = 2³ 12 = 2² x 3 13 = 13 lcm = 2³ x 3 x 13 = 312
