Answer 1

117 (1st option)

Step-by-step explanation:

Given:

`uv^2+5uv+u^2`

To find:

the value of the expression when u = 3 and v = 4

To determine the value, we will substitute for u and v in the expression

`\begin{gathered} uv^2+5uv+u^2\text{ = 3\lparen4}^2)\text{ + 5\lparen3\rparen\lparen4\rparen + 3}^2 \\ \\ =\text{ 3\lparen16\rparen + 60 + 9} \\ \\ =\text{ 48 + 69} \\ \\ =\text{ 117 \lparen1st option\rparen} \end{gathered}`
