The expression that represents another method of computing the product (-1)(6.15 - 3.11) is (-1)(6.15 × (-3.11)).
To find another method of computing the product expression, you can distribute the negative sign across the terms within the parentheses. Let's break down each option:
Option 1: (-1)(6.15 - 3.11)
In this option, you have a subtraction operation inside the parentheses. To compute the product, you would distribute the -1 across the terms:
(-1) * 6.15 - (-1) * 3.11 = -6.15 + 3.11
Option 2: (-1)(6.15 × (-3.11))
Here, you have a multiplication operation inside the parentheses. To compute the product, distribute the -1 across the terms:
(-1) * 6.15 * (-3.11) = 6.15 * 3.11
Option 3: (6 × (-3.11)) + (0.15 × (-3.11))
This option involves addition and multiplication operations. To compute the product, first find the products of each term, and then add them together:
(6 * (-3.11)) + (0.15 * (-3.11)) = -18.66 + (-0.4665)
Option 4: (-1)(6.15 + 3.11)
In this option, you have an addition operation inside the parentheses. To compute the product, distribute the -1 across the terms:
(-1) * 6.15 + (-1) * 3.11 = -6.15 - 3.11
Therefore, the expression that represents another method of computing the product is option 3: (6 × (-3.11)) + (0.15 × (-3.11)).
