X=14
y=3x^2+17
y=3(14)^2+17
y=3•196+17
y=588+17
y=605
Step-by-step explanation:
We have xy = 28, x² + y² = 65 and x³ + y³ = 407.
Since (x + y)(x² - xy + y²) = x³ + y³,
x + y = (x³ + y³)/(x² + y² - xy)
= (407) / [(65) - (28)]
= 407 / 37
= 11.
Hence the sum of the numbers is 11.
5.3/8.8=x/14.3
AB is x,
x= 2.43
