Answer:xy^2+3x^2y;\text{  -24}

Explanation:

The given expression is:

xy+3xy^2-2xy+3x^2y-2xy^2+xy

Combine like terms

xy+xy-2xy+3xy^2-2xy^2+3x^2y

Simplify the resulting expression

\begin{gathered} 2xy-2xy+3xy^2-2xy^2+3x^2y \\  \\ xy^2+3x^2y \end{gathered}

Substitute x = 3 and y = -1 into the simplified expression

\begin{gathered} xy^2+3x^2y \\  \\ 3(-1)^2+3(3)^2(-1) \\  \\ 3(1)+(-27) \\  \\ 3-27 \\  \\ =-24 \end{gathered}

seropon [69]

Answer:

2 \sqrt{15}

Step-by-step explanation:

1) rewrite 60 as it's prime factors.

\sqrt{2 \times 2 \times 3 \times } 5

2) group the smae prime factors into pairs.

\sqrt{(2 \times 2)}  \times 3 \times 5

3) Rewrite each pair in exponent form.

\sqrt{ {2}^{2} \times 3 \times 5 }

4) use this role:

\sqrt{ {x}^{2} }  = x

2 \sqrt{3 \times 5}

5) Simplify.

4 \sqrt{15}

So, therefor, the answer is option 1.
