Question

Evaluate the following expression when x = 4 and y = 5:

Fraction with x squared plus y cubed in the numerator and 2 plus x in the denominator.

3.8
14.83
19.58
23.5

Answer 1

\[\frac{ x^2+y^3 }{ 2+x }\]
Plug in the values

Answer 2

and if there is any doubt about what that means, \[x^2 = x*x\]and\[y^3 = y*y*y\]so you could equivalently find the value of \[\frac{(x*x) + (y*y*y)}{2+x}\]
