1 kg = 1000 g 3 kg = 3000 g 3000 g - 750 g = 2250 g = 2 kg 250 g
a + 6 b = 14 - a - 2 b = - 2 --------------- 6 b - 2 b = 14 - 2 4 b = 12 Divide both sides by 4 b = 12 / 4 b = 3 a + 6 b = 14 a + 6 * 3 = 14 a + 18 = 14 a = 14 - 18 a = - 4
A = Area W = Width L = Length P = Perimeter A = W * L 54 = W * 9 Divide both sides by 9 54 / 9 = W 6 = W W = 6 ft P = 2 ( W + L ) P = 2 ( 9 + 6 ) P = 2 * 15 P = 30 ft
( a - 4 ) ^ 2 = a ^ 2 - 2 * a * 4 + 4 ^ 2 = a ^ 2 - 8 a + 16 2 a ^ 2 -1 6 a + 32 = 2 * [ ( a - 4 ) ]^ 2 ( 64 a ^ 2 ) / ( 2 a ^ 2 - 16 a + 32 ) * ( 2 a - 8 ) / 8 a = ( 64 a ^ 2 / 8 a ) * ( 2a - 8 ) / 2 * [ ( a - 4 ) ] ^ 2 = 8 a * ( 2 a - 8 ) / [ 2 * [ ( a -
f ( x ) = 8 ^ x x = 0 8 ^ 0 = 1 x = 1 8 ^ 1 = 8 x = 2 8 ^ 2 = 64 x = 3 8 ^ 3 = 512
