2√x + 5 + 5y³ for x = 20 and y = -2

Answer 1

Step 1

Write the expression:

`2√(x+5)\text{ + 5y}^3\text{ }`

Step 2

Next, substitute x = 20 and y = -2 into the expression:

`\begin{gathered} 2√(x+5)\text{ + 5y}^3 \\ \\ 2√(25)\text{ + 5}*(-2)^3 \\ \\ 2*5\text{ + 5}*(\text{ -8\rparen} \\ \\ 10\text{ - 40} \\ \\ -30 \end{gathered}`

Final answer

-30
