First look at the leftmost digit, which represents how many 128s are in the number. There is one 128 in 143, so we mark that as a 1. Then take the remainder of the value - in this case 143-128 = 15, and move...

The general equation of a circle is (x-a)^2 + (y-b)^2 = r^2 where the centre is (a,b) and radius r. Therefore the equation of this circle is (x-3)^2 +(y-4)^2 = 4^2 ...or 16 Sometimes its easiest to leave in ...

Lets take 18 and 48 as our two numbers for an example. Break both down into products of their prime factors using factor trees: 18=3x3x3x2 and 48=3x2x2x2x2. Write the prime factors as a Venn diagram. The num...

a) the triangle is isosceles so the two missing angles must be identical. all angles in a triangle add up to 180. therefore, 180-40=140 140/2 = 70* = xb) this triangle has two angles given already, so the sa...
