Answer:
To expand and simplify 4(x+3)+7(4-2x), we can use the distributive property to multiply each term inside the parentheses by the coefficient outside the parentheses. Then, we can simplify the expression by combining like terms.
4(x+3)+7(4-2x)
= 4x + 12 + 28 - 14x (distribute 4 and 7)
= -10x + 40 (combine like terms)
Therefore, 4(x+3)+7(4-2x) simplifies to -10x + 40.
