X+(1/6)=(1/3) get X by itself by subtracting 1/6th from both sides. x(+1/6)-(1/6)=(1/3)-(1/6) x=(1/3)-(1/6) x=(1/6) These operations of getting the variable(s) on one side will be the basis of many of your future calculations as you progress through mathematics.

ok to find a diagonal you use the Pythagorean theorem which is a^2 + b^2 = c^2 ok? c^2 is the diagnol. So basically a^2 + b^2 = 100 ok? so what two squares equal 100. well 64+36=100 take the square root of those two which is 8 and 6. so the perimeter is 28 cm long
