To find the area of a composite figure, separate the figure into simpler shapes whose area can be found. Then add the areas together. Be sure than none of the simpler figures have overlapping areas
X^2 + 8x + 7= 0
(X+7)(X+1)
X=-1,-7
Answer:
mean age of women
(x+y+z)/3=27
mean age of men
(x1+x2+x3+x4+x5+x6)/6=34
mean age of all people in the office
x+y+z=27*3=81
x1+...x6=34*6=204
so
mean age( x+y+z+x1+x2+..x6)/(3+6)=(27*3+34*6)/9
=(81+204)/9=285/9=32 approximately
