Question

Evaluate the following expression when x = 6 and y = 2: Fraction with x squared plus y cubed in the numerator and 2 plus x in the denominator. 2.25 5.5 17.25 27.5

Answer 1

Answer:

Option B.

Step-by-step explanation:

The given expression is

$\dfrac{x^2+y^3}{2+x}$

We need to find the value of given expression when x=6 and y=2.

Substitute x=6 and y=2 in the given expression.

$\dfrac{x^2+y^3}{2+x}=\dfrac{(6)^2+(2)^3}{2+(6)}$

                   $=\dfrac{36+8}{8}$

                   $=\dfrac{44}{8}$

                   $=5.5$

The value of given expression is 5.5 when x=6 and y=2.

Therefore, the correct option is B.
