To determine the two expressions that correctly show the total group of dots in the image, we need additional context regarding how the dots are arranged or grouped. However, I can explain each expression you've provided to help you identify the correct ones depending on the image.
-
4 + 12: This expression suggests that there are two groups—one with 4 dots and one with 12 dots. You would use this if the total number of dots is simply the sum of 4 and 12.
-
4(12): This expression signifies that there are 4 groups of 12 dots each. It would be appropriate if the image shows a total of 4 groups that contain 12 dots each, leading to a total of 48 dots.
-
4(4 + 12): This suggests that there are 4 groups and within each group, there are (4 + 12) dots. This expression equals 4(16), indicating a total of 64 dots if this is the arrangement in the image.
-
4(10) + 4(2): This expression indicates that one group contains 10 dots and another group contains 2 dots, with both groups being repeated 4 times. This expression represents a sum of groups and would total to (40 + 8) = 48 dots.
To narrow it down, you would select the expressions that best match the visual representation in the image. Without seeing the image, it's difficult to definitively point out the two correct expressions. Typically, you would look for ones that either sum correctly to the total number of dots displayed or accurately represent groups as shown.
