Write the conjugates of them then FOIL both the top and bottom, then factor
There's a site called m.a.t.h.w.a.y, and you can type in those functions in order to get the graph ;)
Step-by-step explanation:
area of rrctangle:
12×8= 96cm²
now if rectangle dissapears and then we "glue" what's left, we gonna get two circles
area of circle which gas diameter of 12cm( so radius will be 6cm)will be
πr²=36π≈113.04
another circles radius is 4cm,so area is:
16π≈50.25
sum of all areas: S≈96+113.04+50.25≈259.28cm2
31 i hope u got it right !!
