The steps i took into doing these problems did very well for me
well you cant chose what gender your child will turn up so it can be b/b (boy, boy) g/b, g/g, b/g
(1 + v)(v - 7)
1*(v - 7) + v(v - 7)
1*v - 1*7 + v*v - v*7
v - 7 + v² - 7v
v² - 7v + v - 7
v² - 6v - 7
I hope this helps.
Area of a circle = pi x r^2
200.96 = pi x r^2
200.96 = 3.14 x r^2
r^2 = 64
r = 8 inches
Hope this helps!! :)
(-1/3,0)for the x intercept and (0,-2) for the y intercept
