Calculate the integral of f(x, y)=7xf(x, y)=7x over the region d bounded above by y=x(2−x)y=x(2−x) and below by x=y(2−y)x=y(2−y). hint: apply the quadratic formula to the lower boundary curve to solve for yy as a function of x

answer: the angel abc is 30°,and the abc is a triangle where the angel bac is 90°

so ac is the half of 24=12ft,and from the pythagorean theorem we find ba

ba=√bc^2-ac^2=√576-144=√432=12√3ft

so bac is 12+12√3=12(1+√3)ft

27 +27 or 27times 2=54

the diffrence is 0

if i knew id you bro,, my bad
