Step-by-step explanation:
To find the product of (-35+21)(45-1), we can use the distributive property of multiplication over addition.
The first term in the first set of parentheses is -35, which we can distribute to each term in the second set of parentheses:
-35 * 45 + -35 * -1.
Calculating each term gives us: -1575 + 35 = -1540.
