Expand and simplify y(4y+3)+4(2y+5)

Final answer: The expression y(4y+3)+4(2y+5) expands and simplifies to 4y^2 + 11y + 20. Explanation: To expand and simplify the expression y(4y + 3) + 4(2y + 5), we need to distribute and combine like terms. Distribute y across (4y + 3): y × 4y = 4y^2 and y × 3 = 3y. Distribute 4 across (2y + 5): 4 × 2y = 8y and 4 × 5 = 20. Combine like terms: 4y^2 + 3y + 8y + 20. Simplify by adding 3y and 8y: 4y^2 + 11y + 20. The simplified form of the given expression is 4y^2 + 11y + 20.
