Final answer:
To calculate 7 x (4.32 + 5.11), add the numbers in the parentheses to get 9.43 and then multiply by 7 to get the final result of 66.01.
Step-by-step explanation:
To solve 7 x (4.32 + 5.11), you need to first operate the parentheses, which is addition, and then multiply the result by 7. This is an application of the order of operations often abbreviated as PEMDAS (Parentheses, Exponents, Multiplication and Division, Addition and Subtraction).
So, first we add:
4.32 + 5.11 = 9.43
Then, we multiply the sum by 7:
7 x 9.43 = 66.01
Therefore, 7 x (4.32 + 5.11) equals 66.01.
